IMHO after looking at the pic some more the very best you can do with this picture is use it as a learning experience... and toss it in the don't do this pile. It's one thing if it's candid and that's all you could get, but that hand is too difficult to remove and the framing is dead center which is normally a big no no. At the end of the day you could Photoshop it to death and it still won't make it a great shot simply due to composition and the visual distraction. I have a great many shots like this myself and I just try to see what I did wrong and try to improve on the next one or simply don't hit that shutter until it's perfect (even if it means missing the moment).
IMHO the goal of this should be to look at all the ways you can see an image, recrop, and reprocess to get it closer to your idea of a better image. Below is an original image, it's a piece of crap, but I think the final processing changes it into something that hits my vision of what the images ideal is.
The amusing part is that it was taken with my first digital camera which was a 1mp. To me it shows that vision, composition, and processing all add up to creating the image in your minds eye. Mind you that I do not think this is some fantastic image, but I do remember it as being the image that got me thinking that I could goo all digital and I did when 5mp became common. My inspiration for precessing always goes back to Ansel Adams taking more than 20 years of work to get the print he had always seen for Moonrise over Hernandez NM.
