Nicely blurred out background thanx to a shallow DOF. The background is a little grainy but it isn't such a big issue here. The lighting may be a little too harsh on the tips of some of the upper flowers, but overall a very good image.
I like the composition and detail on this shot... the color looks a little hars and the background is slightly noisy.. maybe from post processing? - setzler
This was either shot at a high ISO or was oversharpened a little. The slight grain in the background gives it away. I reckon it could've been oversaturated a little. The blues are very strong in this photo.
