I will fight

From

You clearly have a handle on semi-realistic female anatomy: she's not twig thin and has realistic curves, as well as an accurate neck width. Her hands look pretty flippin' good and I really like that you indicated the fingernails. Your shading is very dark and clean and your highlights are subtle so they don't give her the illusion of super oily skin. I think the blood splatters on her gun, hands, and bandage are pretty awesome. They look like she's been splattered with blood, which is more than I can say for other parts of her body. I don't understand how the blood got on her shoes and pack, and how they're so spread out. Doesn't make sense that there isn't blood also on the soles of her shoes, which are perfectly fine. Very strange blood placement indeed.

I'd say another area of work would be the expression. For someone covered in blood, she sure seems nonchalant about it. She's not looking at anything in particular, just sort of staring off. Her eyebrows and other features seem very relaxed for someone who's claiming to want to fight or someone who is currently fighting, or any sort of scenario I came up with for this pose. It's definitely the weakest aspect of this picture as she just sort of looks apathetic, not feeling one thing or the other.

I do like the textures you used for the jeans and her hair. Makes them look far less flat than if you hadn't used textures. I can also say that I really like the overall design of this character. Her hair, her tattoos, her clothes; face it, she looks like a badass. At the very least, she's a badass-in-training. Another positive note is that the subtle colors on her face really work. She has a light blush and natural, nude lips that are just a slightly different color than the rest of her skin. I can definitely commend you for your awesome coloring skills. Can't say I have that strong of an opinion on the background, but I can't complain much since my backgrounds are worse. XD
