I like it the shading and detail is pretty good, the one thing I see that could be improved is that the metal or whatever under the eye with that red line thingy over it doesn't really look like it fits in with the rest of it, I think it needs to be darkened in more to fit in with the rest of the head.
It's nice to see you texturing again. And of course, the texture is awesome. It's just great. The mapping is nearly perfect. The shapes are getting a bit old, but they are still awesome. I don't like the eyes much, but they ain't bad.
