The skin and skirt are very nice. I especially like the color of the skirt. The shading of the hair looks like it'll turn out nice. :)
It will be awesome if you finish it. I really like it right now. I think the shirts never looked right is because her top-half above her torso are facing towards the person looking at the graphic, whereas the legs are as if she's sitting, looking to the right for people looking at the graphic. But I've got no right to critisize this as you probably knew that and I've been doing graphics for probably less than a quarter of the time you've been doing them (literally).
