one thing i would pay a bit more attention on is you cutting out. The arms look pretty hacked with bits missing and the fingers on the right arent cut out at all. Just needs a bit of practice though, weve all been there
Goodluck.

Keiley is correct, and i very kind about mentioning it... i unfortunately am not so kind, so i will not say much else about your image. I do suggest taking a look around the net for some tutorials on proper masking and on some of the other tools it appears you used, such as liquify and smudge tools. Good Luck!

Thank you both for taking the time to comment. It is a very poor chop; but probably the most important lesson I learned in this exercise was to pick an image with good resolution to start with.
