I wish I could do this type of photo manipulation (is that a correct term for this shot)? All I know is that when I opened it, I felt like the sun was shining and I was taken in by the glow of the colors you used. It has a dreamy quality and if I shot it I would print it and hang it in one of the dark corners of my home, bringing light and joy to the shadows.
There's a bit of a seeming issue down on the flower with the water drops. Both that and the flower next to it come to an abrupt end. You might be able to clone the yellow one to extend it and smooth that straight line.
There's another one with the top yellow flower that I think could be easily cloned too. That one looks like it was tough to cut out and blend, but I actually like the halo effect on it.
