IMHO, I think that the mesh itself needs more detail.
and, the texture… is a little iffy.
I myself would stick with procedurals and multilayers.
And maybe the eyeballs could use some pupils/irises
It would be more interesting if the black was transparant and the green had more glow and a more interesting pattern. It is kind of, umm, boring as is. Just my opinion.
add more detail and better textures and it could be alright but i noticed you have posted 2 or three different threads her each with slight variations to the name and the modle perhaps you should put it in the wip section untill you are completely saticfied and ready to end it for good
