Hi!
Judging by the pose I understand that this is a throne, but I dont see it as a throne mostly because of the shading but if your intent is to remove it, I wont insist.
Regarding anatomy, (I'm no expert... really) I can spot many problems of proportion and shape:
- head pose seems weird, looks like the head is simply a ball put on the chest.
- bust is very triangular, seems exagerated.
- left and right forearms + right arm need muscles and curves, AFAICS your forearms seem to be elongated wrists.
- right shoulder is not shaded as a shoulder, the left one (even if it seems too huge), on the contrary, make me think it IS a shoulder.
- left legs is somewhat deformed; I dont really sense the calf nor the ankle.
Overall, I like this orangish copperish palette, also general contrast seem ok to me.
