I'm all for a less-humanoid appearance, but I don't know about that design. Its appropriately alien, but the abnormally large frontal portion seems to give the connotation of mental deficiency...or to put it bluntly, the mis-shapen head makes dude look mentally retarded, IMO.
I also think the hairlip is bit disturbing. Like the head shape, it reminds me of a birth defect versus an appealing, unique facial characteristic. I'm also not feeling the booty-chin, unfortunately. The entire lower portion of the face still looks too human, IMO, with the defined cheek lines framing the mouth too well. It looks like a human with very thin lips and a cleft. Perhaps some type of unique facial hair pattern or even some kind of appendage(s) on his chin would do the trick.
I LOVE the eye shape and placement and the "brow" lines on the side of the head are very aesthetically pleasing to me as well.
My .02....I like the 'd like to see you re-shape the head, and try something a bit more risky with the lips and mouth. Great start, though!
