The sketch was by the wonderfully talented ChiByakko, who thinks that Sasuke looks stiff and I think looks perfectly in character.  -_-;  (Doesn't say a lot about Sasuke's overall personality...)  When it was still just a pencil drawing, I decided that I really liked the pic and wanted to color it in.  Once she'd penned it in, I scanned the image (with her permission) and began coloring it.

The result is as you see.  I tried to make the light look like it was coming from above, because I very rarely practice such an angle.  I'm really happy with how Sasuke & Naruto turned out, although the background could use work... If I figure out anything more complimentary, there might or might not be another version up replacing this one.  We'll see... For now, I'll put up this one. ^_^

Oh, and ChiByakko's original sketch (before I meddled with it) is up in her section of the site!  Check it out! ^_^
