Thanks Weyu,
I'm fixing to do a search for demonic heads to get some ideas. I sketched up some ideas last night but I just couldn't seem to get that fierce look I'm after. I think one of the main keys is the eyes somehow. I'll probably spend a full week on nothing but character design.
Don't be satisfied with what you can do but rather strive to do the things you can't do!
Exceed Expectations!
