Whoawhoa, this is awesome. I love the bulldog+fighter it's amazing. Same goes for the rest of ur work so far. This last WIP, you established a mood color of blueish green, and it really works. Your eyes accept the fact that her skin is blue. But what really distracts me is the skull, it only has Blueish Green rim lighting, I think if you give it the same treatment as the skin, so fading it in more by making it blueish green, it will blend in more and keep the focus on that pretty girl. Oh, and now im just being a jerk, but perhaps some lighting of the fire she's walking on on her upper legs.
Do not get me wrong, I love your work, but I thought I'd grab the opportunity to be constructive before I spend the next couple of years stalking you for updates.
