Good concept and color. I like the shallow DOF on the background, but I wish the center of the flower was in focus too, as that's part of the subject. A strong light source on one side would cast some shadows to create depth and help lower the noise levels.
very grainy, and it seems like nothing is in focus here.. if you could get the flower nice and sharp and smooth out the background a bit, this would be much more of a standout shot
This looks sharp, but not in focus. HOwever, I really love the colours - the pink against the green is stunning - and it's an excellent compostion. I love the water drops as well. I'm not sure how you could improve the focus - maybe a macro setting may help in the future.
