My opinion: It would look better with a totally gree leaf, rather than speckled. I can't make out what the blue is under the water and that is frustraiting to me ... but that's just me.
its a neat shot to look at.
its not relaxing though, for some reason my eyes dart all around the leaf and dont naturaly want to settle on it.. the blueness seems like it should be the background and the leaf should be the subject.. but i just keep stareing at the blue.
I think that a crop of some sort(to get the leaf out of the center) would really make this more comfortable to look at. but that just depends on if you want to make it comfortable for me.
did you adjust the colors any?
