I'm not some pro-modeler, so don't expect some expert critiques, haha.
First off, the ears seem a little flat. They don't seem thick and round enough to the in-game model. Probably the first issue I noticed.
The eyes also need some work. The eye socket needs to be taller near the bottom and top of the eye, and also a little bit on the sides as well. Also, the white paint around the eye socket is a little too round without any edges like the in-game model, but doesn't look off at all unless you're really looking for it.
The mouth and cheeks are pretty solid, but the jaw shouldn't be curved. The bottom jaw should be flat.
And lastly for the head, the bottom half of the head shape needs tuning. The top part needs to be more defined, and the bottom should be less defined.
The whole chest area seems pretty well done. No issues with the torso or the bow.
The arms are fine overall, but the hands seem big, and the fingers appear somewhat long.
Legs are pretty good, nothing wrong with them from what I can see.
Overall, most of the work that needs to be done is on the head. Most of the issues are minor. It's not a bad model at all, just needs to be touched up. Hope this helps.
