i havent looked at all the fonts on there, but i found some that would suit my needs if i messed with them a bit in photoshop, maybe you can find some too
about your gfx....
i have to say i like the concept of the last one the most, the colors seem to work the best together in regardds to the bg and the wolf, but not necessarily the text
the first one also has good concept, maybe if the skull has some "grunge" type effects on it, it might get the message across a little better
just some thoughts...
