beautifull shot. However I feel that it is a little week in the Brokeh catagory. While I don't think it will score very high in this challenge> I feel it would scor very well as a stand alone image. As for what i think would help it score better in this challenge. I think it needed a few more details in the back ground to show the brokeh. Sush a couple green lily pads. Or some overhanging branches.
however like I said this is still a good shot. Keep up the great work.
