Prodosh Das Gupta sculptor and Former Director of the National Gallery of Modern Art, New Delhi wrote in the late seventies :

“Kaushik’s love for nature has a particular bias for fauna….to find new and queer subjects and present them in his own inimitable way in paints and drawings. The depiction invariably took a fresh breath of life in the vibrations of blues, reds, greens and yellows.He found pleasure to go deeper into the lives of animals and insects living  on land or underwater and portray them in their vivid form in glowing colour transforming the same in the grandeur of an apparition of colour and formal nuances”
