I really liked the idea of the challenge, but I really failed at the tall pixels part. (In otherwords, the challenge)
I still spent a lot of time working on it, so I might as well post it.
Thanks to joe and ark for crits and comments.
Also, I didn't make the background transparent because it looks horrible on bright colors.

Though I think you could have used a darker pink for the darker shade of the shirt, and some of the outlines are a bit strange, I like it. In particular I think the shading is nice, and the lineart/perspective is very good.
