This is nice.
The first version (black and white) looked better, in my opinion.
The latest WIP is pretty good though.
I dislike the teeth because it looks C/Ped.
I like the bad-ass bling though.
8/10

Looks epic, just sharpen it up a bit.
The bakc of the legs looks very much like a some legs from a Ghiita set I had.

i would add more little details its to blurry and i get fast bored of the head.
it could be much better

It looks good except its a little blurry. The spikes under the jaw make it look horrible. Also, theres basically nothing on the back of the head.
Legs are ok. Too many unattractive lines on the back. You should add more color into this also instead of just red. It gets boring fast.
For now its a 5/10. You should stick to robotic styles ;]

Badabomp

I think that the mouth stretches to far around the head.

I say make it black and white and make the eyes pop our read.

I agree with rum the face wraps around to much.

I also agree with making it black and white with glowing red eyes.

Yea, the face is stretched, but that's not my concern anymore because i sold that head, and i have to make a new one.
It would look like shit in grayscale though :|
I also noticed some mapping fuck up on feet (Those white lines), but i'll fix them later.

One question though: why are you using the head you sold me for your preview? ;o

I'm too lazy to take it off the custom folder and the set looks better with it :D
