In his work Maximov has used traditional methods of enamel art production, without contemporary digital set ovens. During the late 20th-century, Maximov led a resurgence of enamel-based art in Russia. The first exhibition of Maximov’s work occurred at the Podolsk Town Museum in 1979, and the second was held in 1979 at the State Literature Museum in Moscow. Another exhibition Maximov’s work took place at the Kremlin Armoury. In 2012 an exhibition of his work was held in the William Kent House in London, showing his enamel miniature portraits of members of the royal families of the UK, the Netherlands, and Norway. This included the twentieth anniversary of his portrait of Queen Elizabeth II as well as her Diamond Jubilee. Following the exhibition of the works, which can only be seen by appointment, they were put up for auction. Queen Elizabeth II recommended that Princess Anne sit for Maximov the following week, and Queen Elizabeth, The Queen Mother later that month. His work has been a part of around one hundred art exhibitions.
