I quite like the first 3. I like the cat pic, a little different from the normal cat shot. Pics are a tad on the large size tho, 800 x 600 is really as big as you need.
You do some nice experimenting with your camera, you really like to move up close to things, and I like that. Pity about the slightly slipped focus on your cat's face ... it would have been ideal on his/her eyes but slipped to the cheek, ah well. Next time.
I see you also did some nice experiments with lights ... I'll go over there and comment on them, too.
