I recently finished a commission that is a large (24"x36") painting of two rescue dogs: Reilly and Cozmo. I took some progress shots along the way and thought I'd share those with you too.
I initially did a 5x7" color sketch, to work out the composition from the small photograph, and determine colors I wanted to use.
Then, a life-sized drawing to work more on placement and composition. A bit hard to make out here. I scaled it up using a grid, and marked important measurements on the drawing, always helpful in getting a likeness.
