Here's some green inspiration for you. This frog was on the hood of our car the other evening. He's about an inch in length.
This grasshopper on our lamp post is bigger than the frog. He was moving in very slow motion.
There's Gary at an air show we went to a few years back.
Addendum: I was just reading Barbara's blog, Alchemy of Clay, and she mentioned Lana Wilson's article about developing style, it was such a good article I thought I'd also refer to it here.
