Half-Kaizer! Whoa, I thought I was never going to see that again...All right. I'll help, although I'm a sucker at shading as well...
If you simply did a copy and paste for the clothing, which it somewhat looks like (But I don't know...), then there would be a shading problem unless the light source would be from the top down...I can't tell where light sources are though, so I'm just blabbing out a possible if-and-buts situations I suppose. Now that I look at it again, it looks very symmetrical. I'm a symmetry fan myself, but I don't know if that works well in the world of spriting on the front pose.
I like it nevertheless, and his name is Sasuke. Made me giggle a bit, not because of Naruto...Okay, well, yeah, it's kind of like Naruto. But I didn't think much of Naruto with Sasuke...:\
