Hey thanks for the comments on my model everyone
Zandoid: I think with the back the biggest problem is the shouder blades, I made them before the ribcage, and didn't refine them in relation to that after so they are too low. The shoulders are thin because of the posing I did, they are much thicker in the t-pose. Once I pick a final pose I'll do some more sculpting on it to fix up problem areas in the joints like that.
Dilarus: I see what you mean
Mindchamber: Thanks, that weird back hump is another problem from the quick pose I made. I agree the torso is pretty long, I've been debating with myself whether to shorten it or not (the reference I used had a REALLY long torso, I already toned it down)
