Thank you for the input. I'll see if I saved the .psd with the render in a separate layer and take away the red stroke. I was hoping to make this more crisp and clean compared to the picture...Plus, the render I used isn't straight from the reference photo.
EDIT* Without the dark red stroke:
Is it me or does it just seem a little more boring though?
And that headcrab you speak of is the helmet left over from another form he used to have. This is his humanoid form.
