The clarity on all three are exceptional, technically you have shooting flowers down! My only comment is that the crops are a bit too tight... back off and let a little of the background through, and don't center the subject into the frame as much. #2 is the best as far as comp, but its still crowded on the right side. Also - a little vignette to draw the eye to the subject might be appropriate here.. (although I tend not to overdue vignettes, it might make sense here..) The third is my fave - the texture and shadow detail is awesome!
As shots of beautiful blossoms, these are excellent. The color and detail is impressive. As a photo per se, I would just agree that you need a bit more room around the subjects.
