add some lower arms. the flesh color is a new layer with a solid masked out to previous gray blocked area with blending mode set to "color."
add some free hand armor made of blocked out grays, shaded with burn and dodge tool, with red fill layer with color blending mode.
block the hair on a new layer. same way. blocked out with gray for basic shape and went to town with smudge tool.
