Averin learned his technique from the painter Dmitri Yorontnov at the School of Fine Arts "Souvenir de I'An 1905" in Moscow. He is a member of the Moscow Painters Association, with whom he has exhibited on many occasions. For many years he specialised in portraits. His style is purely realistic, with a strong influence of the late 19th century Russian painters, usually depicting domestic scenes in a soft twilight. His realistic painting is typical for the ones of the end of the 19th Century. Like Pavel Fedotov, Averin's favourite painter, he works outside in the air, using surroundings to inspire the brush and compliment the work.
Works by the artist are held in private collections in Russia, France, England, the USA, Spain, Portugal, Italy, Denmark, Japan and many other countries.
