I started this one by quickly smashing some color down and starting the characters form and pose. After two false starts I finally got an angle that I thought I could work with and build on.
I'm not someone who sees an image fully formed in their head and then tries to recreate it. I start with some sketches in pencil or paint approximating roughly what I want and then go in search of some pose reference to solidify it. Google image search is absolutely vital, but more often then not I watch videos. Even when I try to capture a single moment, I still think in motion. When I look at this picture I see the frames before and after it. I could probably come up with more dynamic looks if I could focus on getting one single perfect frame out of the end of the stylus and, in this case, onto the iPad screen.
Anyway, here is another picture and some progression pics I snapped on the way there.
