Just a quick suggestion,

After actually seeing it in-game, the Horns look a bit off. In a sense where as they don't look like they are part of the head , instead they look a bit off as in out of place. they look more like a head gear rather than part of the character.

I Understand that the hair is clipping over them but they seem to bright. Adjusting the colour of them might do the trick. a lighter beige my be the best or adding a but more of a dark shadow on them. So far they look too bright and odd.

Just a suggestion. In the screen shots they look ace but in game they look not right imo.
