I used to be a Character designer for a Japanese Mobile games. This one of the designs I did for them. I have no idea if they used it though lol.
Here's a video of how I colored it. Sorry for the crappy quality of the vid and the sudden cut at the end. I'm still not familiar on how to record my drawings. :)
