An adorable kitten - and he does have a look on his face like it stinks. You might have tried cropping a bit tighter on the left to take out that carpet. It seems a tad bit of detail is lost in the kittens face, maybe a slight sharpen would have helped? This isn't a shot that can easily be redone and capture that look though. :-)
The kitten is adorable and since I own a cat I can smell that box right now (the real one and the photo one LOL). However, I would have tried for a different crop and try to shed some more light on the cute kitten. Good job though.
Cute pose. Might have been a bit better if it were level. This is a difficult shot to get and have lit well. I think you did good with what you had to work with. 5
