Nice! The only (little) thing that's bothering me is the lower right corner (what is that?). But a crop would be difficult (you would lose the person).
But it's a good and colourful pic!
I don't like to make any changes like that to my images, the only things I will change are brightness, contrast and cropping. I have been reading into this a lot today (the ethics of editing photos) and I've decided to go with the changes acceptable to the Wildlife Photographer of the Year competition (Rule 3: http://www.nhm.ac.uk/visit-us/whats-on/temporary-exhibitions/wpy-entry/Rules.jsp) since I hope one day to enter it.
I will just put it down to experience and remember to pay more attention to all corners of my view finder in future.
I'd be interested in hearing everyone's views on this subject!
P.S. Using Photoshop is a large part of my job, and I do like to try different effects on my images and generally messing around with it at home, but if do put them online (if I ever finish re-designing my site) they will be in a separate gallery and not included as part of my photography.
