A set made from real blood soaked tissues.
I'm sure with a little color work you can get them looking fairly realistic...
If you use these be sure to give me credit. It would also be nice to get a note so I can see what you created with them.
Maybe while you're waiting for them to download you could leave me a comment. I'd really appreciate it.
