This is an older sketch of mine, probably dating to a year or two ago, of a younger Shiro. I've not done a lot of thinking about what Shiro looked like back then (my concern has been primarily with what kind of personality he had), but I guess this works...?
The final sketch I scanned into Photoshop and colored, done in blue pencil. I really like the texture and the line quality, but I'm not sure how much it comes across from the scan.
