At all times, artists have travelled the world, soaking up the variety of sensations: creative imagination processes faces, colors, picture of nature and the city, and in the furnace of consciousness other pictures and images are smelted, which are different from the original ones, but still give the viewer an opportunity to feel the empathy.
Immediately after completing the postgraduate studies in 1991 Diana went for an internship to Italy. For four months she lived in Rome, went to museums and walked the streets of the legendary city with a sketchbook, painting portraits and landscapes. Among Diana's Roman portraits there were: Boncompagni Princess Ludovisi's portrait, representative of an ancient aristocratic family, portrait of the banker Federici and his wife Marizella, who played the guitar and sang beautiful Italian songs during the painting session. Everything she knew from books appeared in person before her eyes. The restored frescoes of Michelangelo irritated her by their "smoothness"; the city struck her with culture infused through the ages, and people – with caring attitude towards their cultural heritage.
After Rome there was a trip to Thailand and Cambodia in 1995. International Red Cross bought a few Diana's works and paid for her journey. Thai and Cambodian temples captured the imagination. The lack of modern culture and art was surprising, only ancient monuments were present. In Phnom Penh she attended an anniversary ceremony of Prince Sihanouk's sister, where Prince's younger sister gave her some exotic fruit, and said that the next incarnation of Diana shall be in the capital of Thailand in Tambourine Chinatown in a Brahman's family. It sounded strange to her Orthodox ear, but she complied with all the necessary standards and as a guest of honor handed cooked treats to the monks. Because of spicy and unusual food there was a feeling that the head expanded, as so many new echoes appears inside of it towards the richness of taste sensations. Cambodia shocked her with terrible poverty and the lepers on the streets. In the ancient temple complex of Ankorvat a charming six-year old boy Paul being her guide walked Diana thorough stone labyrinth and helpfully brought water. Back in Moscow she created "The Emerald Buddha" and several portraits of Buddhas and Apsaras.
In 1996, the Palestinian Ambassador in Moscow, Daur Barakat, whose portrait Diana painted, invited her to visit Tunisia and paint a portrait of the famous Gorbel family. Diana lived in their house, painted portraits and travelled the country with them. In Tunisia, her solo exhibition was held; it was visited by the Russian consulate employees that offered to place her works at Russian cultural center. Diana agreed. The Russian Embassy in Tunisia invited her to take part in the international festival in Mahares-Sfax, which annually attracted artists from around the world. There Diana was the only artist representing Russia. She had been painting portraits for two months and was honored with a gold medal for performing this work. It was in Tunisia that Diana Vouba met legendary reconnaissance scout Tatiana Matthews, English subjects, and worked on her last lifetime portrait, her heroine was 96 years old at that time. Immediately after the completion of the work on the portrait Tatiana Matthews dialed the BBC number and put Diana through to the host, she answered questions and talked about the situation in Abkhazia for 10 minutes live.
In 1997, the Martin Gallery in Basel invited Diana to organize her personal exhibition. On the first day 11 of her works out of 21 presented at the exhibition were sold, and by the end of the month – all of them were sold. Then there were two more exhibitions - in Basel and in Zurich.
In 1999, Diana went to New York thank to the invitation of the Grandt gallery. Months, during which her solo exhibition was held, flew by very fast, she worked hard painting portraits. She met with major collectors of contemporary art -Tatiana and Natalia Kolodzei, who added Diana's works to their collection. In 2001, the Union of Artists of Russia offered Diana a trip to Paris. For several months she worked in Paris in "The City of Art", certainly, went to museums and walked the city streets, the Seine fascinated her, the river truly has been the main artery of the city, and all life revolved in the orbit of its waterfront and throbbed on its waters. In Paris she painted a portrait of Madame Bruno, the founder of The City of Art, pilgrimage place for artists from around the world. She was painted by a lot of famous artists, including Georges Braque, but out of the 200 portraits painted by different artists in different times, Madame Bruno liked the one painted by Diana so much that she decided to hang it up at her home, and offered Diana a solo exhibition at Cité des Arts.
In 2001, Diana took part in the "Abstraction in Russia, the XX Century" exhibition, where all three of her works were exhibited in the Russian Museum.
In 2004, along with her son Alan, she performed a pilgrimage to India, for 40 days they've traveled the holy places, saw Delhi, Kolkata and many other cities. While being on this trip they participated in the ritual of funeral, and the smell of smoke rising from the burning body resembled the smell of a usual kebab so much that she and her son could not eat meat and became vegetarians for two years after that. The Hindu themselves say that in India everyone can find what he or she seeks: Addicts - drugs, drunks – alcohol, and Diana found spiritual beauty for herself there by meeting with a famous guru and talking to monks and ascetics. Being back in Moscow Diana implemented two new projects "Tetris" and "Ocean City", connecting Moscow, the city where she lived, with her impressions of India. "God created an ocean, a man build a city."
In 2005, Diana painted the walls at Rondine in Italy, while living in the "Casa Leonardo", and the view from her window was exactly the same as the scenery behind the Mona Lisa's back.
In 2007, she visited Brazil thanks to the invitation of the Russian Consulate General in Rio de Janeiro. She was asked to paint the picture for the embassy. Thus, "Red Moscow" series had appeared - four towers of the Moscow Kremlin and St. Basil's cathedral dome that she had presented as a gift to the embassy, which then organized her journey through the country in appreciation of it. In Brazil, she got acquainted with Oscar Niemeyer, an outstanding architect of modernity. The capital of Brazil has been completely designed by him, but one couldn't find two similar houses, the architecture of the city has been a blend of innovative ideas and colonial style. The Brazilian air was saturated with fantastic flavors of the tree of life, mango and jasmine. In Rio Diana met Tamara Fedorovna Ribeiro, Russia's native, who at the age of 16 went off at the front, was imprisoned and found herself in Brazil by marrying a Brazilian. She was a very wealthy and cultured woman, known in the country. Accidentally during the festival, they found themselves in the room at the neighboring places, started to talk and became friends, and Tamara Ribeiro showed Diana museums out of tourists' reach, helped her to understand the country and feel its spirit. In general, as Diana says, almost all of those people, whose portraits she painted, as well as many buyers, later became her friends.
