the composition is good, the wave on the right may be drawing my eye over there so you could crop it out. I added a version I played with in PS, yeah I know it is 'cheating'. I pumped up the saturation and balanced the sky a little. A lot of people heavily PS on UF which adds heaps of impact especially with those tiny thumbnails. To get more people looking and commenting the thumbnails have to have heaps of impact and usually a comment on someone elses picture gets one in return as well.
