The composition looks good but (at least on my monitor) the image seems a little dark. As such it also seems a little soft. I like the catchlights in the eyes.
This is my second go around =) - Awh... very cute! I think the spot on his nose is a little too distracting... I would have tried burning it in a little, looks too over-exposed. Also, the picture looks like it is not really sharp... looks slightly blurry. Otherwise, very good job =)
Do i Recongnise this cat? A little soft on the focus maybe. Still a nice shot. If this is the cat that i think he is; i thought there might be a shot of him brushing his teeth. :)
Good luck with the challange
