Pretty cool, but the eye's are kinda out of place, a bit bigger and closer together . . . Also when you go to make the spinny, make the index to n 0, it makes the quality much better.
also, it's cluttered at the back, try to keep it the same around the entire head.
Well you certainly achieved you goals!
First thing that struck me after "Wow, pretty lights" was that the eyes seemed too dull compared to everything else. Adding the same cyberlooking glow would be really fitting I think.
I like the hexes btw ^_^
