ooooh I like it I think all it needs is some shading and detail on her upper body and somethin to fill the background maybe extend the skulls behind her and make the shining around her head a little more dramatic?
maybe add some detail to her upper body. Even with the police tape, it just seems to have a lot of empty space. I might suggest a center button line or some folds to create a look of cloth. just some suggestions though. I really like the picture overall! ^_^
