Those eyes map awesome, look awesome too. It almost has an alien fish type look to it to me. I would try to do similar textured hands, but then maybe armor the rest of it. The sort of reptilian fish look makes me think the visual elements of gills in the armor. Maybe even some scale type armor on the stomach area of the body textures. It might look cool if it looked wet, kind of how giger liked to make everything look wet and slick.
Just my 2 cents, no cash value. Cool head either way, I've always enjoyed your style.
