i'm no expert in this but to mee anatomy looks somewhat off... some major points that come to mind could be:
- fingers, they taper too much and are maybe too long
- feet definetly too long
- waist seems a bit too large but it could also be that the torso is too small
- the face looks really strange, eyes are too high, nose and mouth too far aparth, nose not large enough, also maybe cheeckbones are too close to the nose...
