The hair is correctly made, nice colored (as the rest of the drawing). Lights and shadow in the right place. Now the blood. I think its cool, the bruise in her forehead isn't flowing according with her head, what is ok: depending of the hurt, blood may take different forms. There are only three spots that i would like to advice you. 1# : The cut in the middle of her shirt, show the skin but not the rest of her breast. 2# : Left eye don't look for the same direction as the right one. 3# Her right shoulder, where the shirt was teared, suggests more bruises on that part. Thats all, my final veredict is: its cool and well done, just some little mistakes. Nice job.
