Random sprite

[Chaoxys]

I'm having trouble with this sprite. It's essentially going to walk around, the top of it's head is a platform, but it shoots fire from time to time so you have to get off when it does.

Either way, for right now I need some help getting the shading on the chin/jaw to look right. The shading is from the top left and I know the shading as of right now probably doesn't look right, but the issue is when I tried to change it to be more fitting... idk, it just didn't look right. Any suggestions?
