Ok.. I wrote a lot of stuff, then my computer shut down.. So I'll write a little.

So, good to see that there are some people attempting this

Razasha, the face doesn't look 'angry' enough, if you could add more detail to the 'hair,' and bring the back up a little. The black markings are too faded. The three lights down the front of its forehead aren't lit up.
Also, I'm not sure how it might look, differently, but I don't like the grills and the 'snout' on the face very much. I'm not sure if it's just the size of them, but yeah.
And I can see you payed a lot more attention to the front of the head, but maybe you could think of some extra details to add to the back too.
Thanks.

And as a side note - which I will add to the first post - any C/P'ing will decrease the amount which you might get if I choose your head.

Cheers all.
