Here's a recent drawing I did for someone of their pet dog called Ice.
I was given a photo of the dog to use as a reference.
It's an A4 sized drawing (21cm x 29.7cm), drawn on Canson Bristol board.
I used various grades of pencil ranging from 8B to 5H, HB & 2B mechanical pencils (0.5 mm), normal and putty erasers. Blending stumps, tortillions, cotton buds and tissues were used for blending.
