The top image is your original post and the one below it is my post-production work to it. The first, major adjustment was to the horizon to have it, well, horizontal ... lol Maybe it's just me, but that has always been a pet peeve of mine and my eye goes to it immediately whenever it's askew. I also cropped the sky back a bit as I found you floating too much in the frame.
Besides that just a bit of color and contrast tweaking, some level and curve adjustments, cloning out some elements I found distracting (shoe straps next to your leg and a few of the people down on the shoreline) and finally I dodged a little around the drink, your hair and the swell of your breasts to make all pop out a little more.
Oh, wish that the person shooting had kept your entire hand in -- I semi-fudged part of it in but would have been better to have it in the original. [img]/ubbthreads/images/graemlins/grin.gif[/img]
For straight out of the the camera ... a Canon PowerShot S1 ... it was very nice file to work with.
