Its seems like the clown from:
Twisted Metal well.. thats how i see it
and im loving the head except the whiter parts around the eyes, seem to need a little more of the texture that all the face had
9.5/10
keep up the good work

You may know R4ff's head which is pretty similar.

Jesus, didn't know that you're so pro D:
The mouth lookes mirrored.
Make the blue lines, which go over the eyes, more realistic, so they fit with the whole head which is actually pretty amazing

good job with the head, you will sell it later?

@chreeys .. yeah the mouth isnt finish yet , he will lost a teeth later and get different shading ..
well ,things on my list to post a new wip
-teeths [ ]
-tongue [ ]
-chin [ ]
-(maybe)change the colour from the mouth make-up [ ]
hmm im not sure to sell this head...its like a baby for me :*D pretty hard work with paint.net ... :/

epic head but mouth doesnt realy suit it

I love everything about the clown it is worth so much and has so much value.

I love that mouth.
So much that if a girl had that mouth...... Well... I don't know where i was going with that but lol, the only thing i see that sticks out are the eyebrows. Maybe make them look hairy instead of just lines? Besides that awesome c:

I love the detail of the face, but try to make the head to look more like a mask, it would be better.

i find this head confusing, the cheek bones and grunge texture over it suggest that its a skull, but then it wouldnt have ears. i would suggest either making it more skullish, removing ears, replacing them with holes etc, or redoing the cheek bones to make it more, skin like

the mapping and shading of the blue stripes is pretty boss, really like how you did those
the drawing work and shading on the rest is mediocre, think with your drawing style, it would look better vectored/vexelled
teeth are drawn really well, proper attention to the shading would just do that much extra
ears are, well, yeah, not great, assuming those were rather rushed?
styling is pretty average, lacks refinement
grunge texture is a bit blatant, would soften that, does it leave a seam at the back?

overall, i think its quite a good attempt, not quite on the level of QC3's version of it, but good nontheless
