Horn looks weird
Eyes look weird
Mouth looks weird
Nose looks weird
It looks weird, you should try and make the face smaller (shrink the eyes and nose, maybe put them more up and closer together) and make focus more on the eyes and horn. The beanie/hood thingy is WAAAAAY too far up, and you need to move it down.
The horn itself looks 2D and very thin weird at the top. Really work on that.
Overall I'd give it a 5/10..
