Drawing is both an artist expression and a way to understand and study the subject of the art. In this case, using some photos I took at some various zoos, I did studies of two species of rhinoceros. The head studies of the black rhino really helped me get proportions and details correct with each attempt. I usually do these sketches in pencil or pen, but here I use washes of Indian ink on paper. This is a slower process, but the result was very satisfying. Colored versions of the Greater One-horned rhino and baby can be purchased here. And the Black rhino head study can be purchased here.
