WOW! I love both of those. I agree with Fellah in that in the color one, the background detracts, but I still love the overall image. Although I'm a huge fan of b&w, I think that I actually like the color one better.
Definitely do the "Nightmare Creatures"--sounds like a great idea and, if they're as good as the bunny, I for one would love to see them.
And todays two posts, say wich one you like the most!
