Pyne is one of the most notable contemporary artists of the Bengal School of Art, who had also developed his own style of "poetic surrealism", fantasy and dark imagery, around the themes of Bengali folklore and mythology.

[5] Also during his childhood years, he flipped through, Mouchak, a Bengali children's magazine, to which his family subscribed, he came across a printed drawing by, Abanindranath, the founder of the Bengal school art movement.

[5] Further he added the influences of Frans Hals, Rembrandt's handling of chiaroscuro and Paul Klee's simplicity and cubism in developing his own style of "poetic surrealism", around themes from Bengali folklore and mythology.

[11] Though, he was never prolific, continued to shun both limelight and art collectors alike, and never held any major exhibition, preferring to show his paintings three at a time, as Society of Contemporary Artists, Kolkata to which he belonged.

[1][5] In his later years, Pyne undertook a series of works that drew from the Mahabharata but focused on the peripheral characters of that epic such as Ekalavya and Amba and these were exhibited in Kolkata in 2010.

[11] Pyne started as a water-colourist in the Bengal school mode, and gradually shifted to gouache and finally to tempera, for his subsequent abstract and surrealist work period, in ochre, black and blue shades.

[17] The art critic Ranjit Hoskote termed him "a poet of melancholia", who "explored elements of the subconscious; the mercenary, the demons and the angels were aspects of the self split from his waking reality"[1] while Pritish Nandy described his paintings as having "a meticulous narrative quality[...]that is taken from the dark innards of his imagination".
