here you go mate. i'm pretty tired but i manage to do a quick paintover. in general keep in mind everything Denis said. Plus I toned down saturation and added a complementary color, to catch viewers eye. Changed a bit composition to give this guy some breathing space and threw some light to pop those shiny armor and make the head read more 3d. hope i make sense and it helps. forgive my language i'm a no brainer atm. love the design. keep on rockin' ;)
