New! Denied?

I am thoroughly frustrated right now. My new wallpaper, and possibly my best, has been denied. I can't find any reason for it really. It's got a blood splat on it, but I've seen that AND worse on other peoples' art. At first I thought it was a technical glitch..but I resubmitted it and it still didn't accept it. Does anyone know why? You should be able see it below, unless TheO is really in-depth about censoring me..
