3 - Mainly for the potential. Like the concept, good colors. Criticism; if that pistil/stigma were nice and sharp, even if nothing else were in focus, would have made this much better in my opinion. Perhaps a variation in the composition too, with a little more space on the left and a tighter crop on the right, may have also made this better, not sure.
Definitely a lot of DOF there, but the subject in focus is almost too small for the picture - it's getting minimized by the background blur. Meets the challenge very well, but not as appealing to me (JMO).
