nice colors
This is pretty good. Very nicely stylized and the background compliments the girl wonderfully. The roughness contrasts her smoothness, and the colors make her hair and the purples in her skin pop. As far as the shirt goes, I think it's actually better than you think. The folds in the fabric look good, and the pattern doesn't seem disjointed or anything. There is something weird about her shoulder, though, at least for me. I think it's a little off because the sleeves have a lot of folds but there's not even a wrinkle in the section between her sleeve and her hair. You don't want to go randomly plopping creases in but at the same time, that area looks a little flat to me. Maybe a little more shading would help. Other than that, I think it's great.
