Moejoe did the first version of my book cover, which you can see in this thread here.
I totally loved it, and it only took him about 2 hours from the time I posted asking for help.
The only reason I changed the cover is because I needed one 300 dpi for the paperback version, but even working from his original idea, it took me a couple of months to come up with the final version.
The tagline is his - it was too perfect not to use (and the fact that he came up with it from a two paragraph synopsis is just astounding).
He has a gift.
