the small horns look good, but the long one's a little awkward with the mapping, other wise great mapping,
however, the back of the head looks like it's rather barren (based on the flat alone)
The past makes you wanna die out of regret, and future makes you depressed out of anxiety. So by elimination, the present is likely the happiest time.
Not sure if I should keep the hair/spikes sticking out of the side of the head.
Oh and, I'm still trying to figure out how to make the face match the rest of the head without making it look like it was just pasted on.
