I think the flash was a little too strong for her pale skin. But, also, I don't see why you skimped so much on making her actually look like a zombie and then shoot at an angle that cuts off whatever blood there was.
If you look through my port, i'm a model not a photographer. If you looked through the port you would see there is a series of images from this shoot that progress with the "zombie infection". I only have make up on that shows me bitten.
Nice outfit and hair, but maybe another background might have fit better? (so your shoes would be better to see). I personally canīt really see the "zombie" in the photo, but I like it, especially your look and lips are delicious!
