Okay, I was expecting to see this nurse covered in blood, but not like THIS. It doesn't even look like blood, it looks like she put a giant tattoo on her body. I admit that all of that stuff makes her look a bit undesirable. I will give you credit for being creative. I looked at the stuff on your website and couldn't find anything like this! I guess a mainstream website is a more suitable place for this.
I didn't even notice the butcher's knife she was holding up. It's just that everything is covered in blood so much, it makes good camoflauge. Yes, and she's licking it too. The could probably have been some background. Then again, it does contrast well.
