side profile is great.... I would even push it a bit further but that's just me.
the front profile is what's lacking here. the shoulders stick out too far, the hips are thin and stiff looking, the torso is a little bulbus.. the top of the torso is very straight and rigid..
the side profile is nice and flowing, but the front profile is very stiff and combersome. i'll bet if you got some interesting reference and pushed the curves and shapes of the body from the front view, this thing would start looking pretty fucking awesome pretty fucking quickly.
I did a really quick paintover for some ideas for making the front profile a bit more interesting. i just did the torso, and I'm not so good with 2d, so take it with a grain of salt. I hope you don't mind...
