I have an idea this photo made me think of.. and I figured maybe you could do it since you're quite into the beauty of gore.
There's this movie called Idle Hands I don't know if you've ever heard of it or seen it but there's a part in it near the end where a severed hand (Concept : Idle hands are the Devil's play thing) Anyways this severed hand is in a school room sharpening the tips of it's fingers. Making them well.. sharp and pointy.
Okay here's my idea that I thought you might want to try out:
A beautiful girl much like that one up there using a severed finger sharpened and bloody. She uses this finger as though it were a tube of lipstick.. putting blood red lipstick on. And there can be the whole dripping blood effect as well.
If I had the funds to do that sort of picture I deffinately would. Sadly I don't and I was wondering if maybe you could put my idea into effect. Don't let it go to waste you know.
