New version of the Pliskin Alien. I think it is getting close. No need for painted textures. I just made some in Maya. I might mess with the lighting a bit more and then do some finalized renders with AO pass.

[Edit]

Here is a better version composited in Autodesk Composite that ships with Maya. I did some color correction and added the reflection of the earth in the eyes. I think I am liking the direction this is going in.
