Really looks like Sheik. Good job with that.
I like how detailed and well done the head was, but it seems that the other parts were lacking in terms of shading and detail.
You did a great job making the set completely the same as the character.
The hair looks so flat compared to the face, sup with that?
The problem isn't the thickness of the hair, the problem is that it lacks depth, it looks completely 2d. I know this texture is probably done but on the next attempt think 3d, make the hair follow the contours of the head, make the highlights on logical places and make strands of hair go on top of eachother in a 3d space (if you aren't planning on something cartoony ofc)
I don't know if realistic is what you should go for, but concider something like this maybe?

I don't know, couldn't find any good examples but.. Its close enough.
All that at the side I think your face drawing is excellent, slightly bad mapping on the side of the stomach textures and at the top of the hands, but keep on doing this stuff, you are good at it. I know how time consuming this stuff is.
