DUDE Gerbill!
I mean I ain't that good with female proportion, BUT her boobs are WAY too far down on her chest and well the lower part of tha legs are too short. Knee should be higher up.
I just noticed something on mine too, her boobs are like just one big curve they look hugemongous they oughta be curved a bit differently. Anyway. The chest are is one of the most difficult thing with drawing females.
