Finger Poseable Vortigaunt

I made a fingerposable Vortigaunt as a request [link] i'm not sure why the skin is like that I haven't changed anything in that area O.o

The eye and face posing are mostely intact theres just some wierdness that adds to the overall diseased look :S

I think it works quite well as a model but i'm guessing its not what they were after.
