I took a bit of a longer lunch break, since I got here at 8:15AM this morning, so I did a pen sketch of my computer mouse, and then I colored one of them with my cool gray Copics (well, it was more of a value study, to be honest, but it's all dark colors anyway, haha!)
Image 1: The pen sketches - 15 minutes for the whole page.
Image 2: My Copics work better with the copier paper at work than they do with my friggin' cheapie sketchbook. SAD.
