Nice drawing, I like the shading. I would just suggest that you use one of the distort filter's to put some bulge on the hexagonal area's of her suit. Most of the shading is very 3D, and the hexagons are a nice detail, but right now they really flatten those areas out because the lines don't follow the contour of her body.
Kind of should have placed her on a background of contrasting color... to make her pop more. She just kind of blends into everything else. Nice drawing otherwise. One of your more anatomically correct ones, I'd say.
Dude, one more thing...How do you choose colors when painting a character so that they CONTRAST well enough to make the picture pop? I can't seem to do that w/o using references and such, whats the principle behind it...also, you last tutorial you mentioned "areas where there's more blood" tends to be redder, how do I find out which areas are redder? Thanks!
