I like the flowing water/bubbles, eye contact. What a bill. A bit of an awkward pose.
I might be tempted to tone down the upper background just a bit more, try to match the luminosity of the tan in foreground.
Thanks for all of your comments and suggestions, I agree the top is a bit of a mess so I have tried a combination of cropping, pasting and cloning, I am more used to getting rid of twigs:)
