Here is my second image I've done while on vacation! Using a roller-ball mouse is proving to be a challenge while coloring. I'd love to add highlights and shadows but just don't have enough control.
My only supplies are my blue gel pen, my digital camera, and access to a MAC laptop with the roller-ball mouse. I'm drawing on the back of scratch paper which is why there is lettering showing in the top right corner. The edges are blackened because of the flash while taking a close up picture! All part of the "rough" process.
