I love how you capture that goofiness, craziness, humorously graceful and, I'll admit it, lazy personality of cats in this photo. The cat looks perfectly comfortable is this position, and he's not giving up any secrets as to how. His (her?) expression almost invites me to try it.
The colors are really vibrant, giving everything a hyper-real quality. From the background, to the kitty-cat himself, the colors jump out beautifully. It's really hard to get over the eyes. The green with the multi-colored flecks draw the attention and make it difficult to look away.
I am taking away a couple of stars for originality, because everyone takes pictures of their cats. However, this is one of the most beautifully and humorously done that I have seen.
