He was particularly noted for his masterful drawing, his harmonious, if not particularly vivid coloring, the ability to capture a close resemblance, appropriate lighting, and in general for his conscientious execution without embellishment. Contemporaries highly rated his portraits, consequently he created many works of this sort. Particularly striking are his many portraits; a portrait of Madame Khatova (the wife of General
Alexander Ilich Khatov), a life-size portrait of Count
Alexander Stroganov, a portrait of the former president of the Academy,
Alexey Olenin, and the paintings "Head of a Young Turk", "Boy with Dog", and "Fiddler". In addition, Varnek painted icons representing the
Annunciation and the
Four Evangelists. These latter are in the chapel of the Academy of Arts. ==Selected portraits==
