heres a concept and a wip model … need to go into more detail 
crits & comments please !
a little bit more finetuning … now rendered with vray in max
i still have to work more on the eyes …
c&c please
heres the wireframe
Haha! Great design, not something you see everyday! Maybe you could give the skin some color-detail? I can imagine that his skin looks different round the eyes than on the top of his/her ‘head’… But offcourse, it is an alien so I might be wrong. 
I hope he has tentacles! Really cool character love the barcodes.
another version of the head … with a little texture change … and a quickly built environment . 
Cool! That environment is great in its simplicity!
