The thing that really stands out to me is how he's holding the bow. You pull back the string with three fingers, which are curled around the string, not the tips of the fingers. And if he were to aim that bow with his hands like that one of his hands is backwards/upside down.
I'd point out that the string being pulled is curved, while it should have tension. An archer also would not be pulling the arrow back unless he was in a ready stance and looking down the arrow. The way he's pulling it back right now, the string is just going to press into his side long before he can draw the arrow back far enough.The clothing needs a lot of work, in both the sculpting and texturing stage, and the texturing & posing of the face need a lot of work. Can you show your sculpt?

It'd rework all the clothes. It overall reads lumpy and not real. Almost as if real clothes were not referenced.
