Okay, so, honestly, I don't really like the overall look.
Lips are really thick, don't look like his and also don't match the expression I want.
Ears are quite... weird. Take a look at the side-view reference picture.
Nose also won't match his expression (yeah, srsly). His nostrils are more lifted than they should be.
Dunno about the hair because I can't go ingame right now to check it out and I don't know what to say about it for now.
