Hoth needs help de-crapifying this sprite

[ngaurhoth1]

Um so are there any more improvements you guys think I can make to the face? I kind of don't want do another light source because of what the face is really for.

I plan on making this into a whirlpool with a face, or Charybdis if you'd prefer to call it that.

Before I started the actual whirlpool part I wanted to get the shape and shading of the face done first.
