Digital Art Trying to make graphics again

Well, I only have this one right now (which is my avatar.)
v1.
v.2

V.2 has bits of orange to work with the Portal theme

CnC?

EDIT:

V.3

 

I really can't see any "orange" in v2. It's also too bright, level the brightness down a bit, and give the avatar some depth and some more colour.

 

I'm not 100% sure how to make depth..... I did lower down the brightness... Added orange over the orange eye guy



CnC still?
