First of all...this is an adorable kitten! And he's got some gorgeous eyes! Cats are great subject for photography, when you can snag them in mid-motion.
I love the perfect pose you caught him in. He really does look like he's dancing, and you see all the feline grace and delicacy in this picture. (Even though we all know cats aren't always so graceful )
The main thing I saw...was that the tip of his ears and paw are cut off...and he looks slightly crowded in the photograph. If you could have zoomed out, just a little, I think the green around him would have framed him perfectly, and he wouldn't look crowded.
I love the orange color against the green, I thought that looked really neat. Maybe a tad bit of contrast could make that really stand out?
