I had a similar idea and didn't do it because the holier than thou Nazis of DPC would refuse to see that it's just a photograph for a beginning of the end challenge. At least you had guts. Good luck!
I like the use of light and shade in this shot as it gives it more feel. The blood should be running though, not globby (this is a fresh cut after all). I have a great recipe for blood if you need it. I used it for my image, the other razor cutting wrist one in this challenge. Mines getting hammered.
