When i saw the first pic, i thought that the left pink thing was eye, and when i saw the second pic i thought those demon coloured parts were eyes.
You should really work on making them look like eyes, and lower them aswell.
That thing on forehead is pretty great, and it's nice to see someone making something else than platinum-demon-void coloured robotic heads.
The front is the only thing I understand about this head, I don't get the sides and the back.
Did you finish your emo head? I really want to see more on that, can you link me that if you are still working on it?
It looks very clear and high quality ish for now. The front seems a little bit plain, unless that's what you're going for.

great, the emoticon on the top of the head is perfect, and the green eye idea ? nice 8/10. keep it up. maybe you should change the pink colour into blue, or some yellow.
A quick note: I'm about halfway through turning that back into a psd.
This is definitely interesting. But please, don't post a preview thats 3000px wide. My screen hurts.
However, you need to consider the lighting. Shading is good, but it needs softened highlights to really come together.
