I LOVE th coloring on this! It's so soft and smooth~ My favorite part is the leather/cloth on the right breast (our right), the material comes out in a really great way :3
I also love her expression! She looks like she's gonna shoot someone in cold blood the next second X3
My only criticism of this is that I don't think the foreshortening of her raised arm is really working, I think her elbow area should be a bit wider, to better the illusion of it being closer to the viewer. BUt other than that, I REALLY really love this!
