This is gorgeous! I love the highlights, and as far as I can tell, the proportions are great. I really like how their's a distinct difference between objects of the same colour, but different material (e.g. the boots and her vest). One thing I would suggest is deepening the shadows - especially in the background - which will help it look more life-like. Great work on the blood - you really conveyed the right level of viscosity.

(also, this would make a great print!:3)
