I'm going to take a whack at this, if you don't mind. I'll post my result up when I'm finished.

Done! Enjoy.

Is it too small?

I'm not sure if this is what you want... But I took a hack at it, and this is what I got. I couldn't decide between the two that I had created.
P.S. The little render in the middle is a skull.
First One:

Second One:

Quick question, do you have a rough size estimate on how big you want it?
If you have any prefrences, please PM me
also if it wasn't obvious I'm going to try this

I'm not going to PM anyone to avoid giving anyone any advantage over others. The size is about that of an usual banner... Or thats what I thought, you can get wild with that too. Really the only real requirements are stated in the first post.
E:
crazylars, that is too huge, we wanna actually use it somewhere. And I really don't think a giant drop of blood and some text is gonna make it.
Frost-Dragon, I like that, but there is maybe too much background showing and also I can't see the word Blood anywhere.
5n1p3r, no offense but this looks like something you made in 5 minutes.
guitarookid, Well, it's well made whatever it is, I kinda dislike the whole consept.

Protip for those that actually read comments: I like blood splatters, and as I told before, vampire is my favourite color for blood.

E2: Thanks for all congrats.

Looks like I'm starting from scratch, then. I'll give it another go.

do u have any constraints? such as size and time limit?

I like guitarookid's logo the most, it has creepiness in it. Background looks like a floor where has happened huge bloody accident, and otherwise it has insaneness in it.
But still, it's not what I was waiting for.

Also, holy shit guitarookid, haven't seen you in ages! :o

And again, thanks for the congratulations! We really appreciate it.

I think we should keep this going until we can find the right one...

Agreed. Adding to first post.
