I dig it! : D It's going to look super-cool on fliers.
I recently borrowed my art teacher's Graphire 3 so i could finish my Sakura-Con mascot entry in time.
As you can imagine, I got tired of coloring the same piece for hours at a time, so I goofed off.

Time: around 30 minutes in Photoshop CS4
I didn't use any reference material, but I probably could have so it'd look a little more accurate.
