The upper body seems a tad large compared to the legs, especially when comparing the arms to the legs. But if you're going for that style, then it's looking pretty good so far.
I guess it just looks a little weird to me because arms are generally not as thick or as long as legs, and legs usually seem more realistic if they look like they can support whatever is on top of them. Anyway, ever since I got into 3d modeling myself, I love seeing other people's 3d model work. I'll be keeping my eye on this.
