Personally I love the way you've styled the proportions ^^
Two things: I too think it'd be cool if you made the pants longer. Adding some folds that fall around the shoes would really make the lower part of the model look way more interesting.
The head face looks borked. Perhaps you're not done, but there's really no definition of the features; the cheekbones barely register, the mouth isn't shaped right, and all together the features look a little bit too high on the head.
It also doesn't look like such a realistically styled head fits well with the stylized body.
I guess a lot of my crits could be due in part to the strange perspective, but I think that's only a very small part of the issue.
Overall, nice job ^^
