I know ive cheated with this one but I'm slightly obsessed with greys & this piece is a homage to the book 'Communion' by Whitley Streiber, so I had to take part in this thread.

The grey head was V2 made as alienistic as I could with Poser, then the mesh was 'softened' in Amorphium & rendered in Bryce.
The rest was done in photoshop.

Anytime I see something screech across a room and latch onto someone's neck, and the guy screams and tries to get it off, I have to laugh, because what is that thing?
