Very fine picture, but I think it would have been even better had you cropped out the top 20% of the picture not only to focus on the stamens, which are the point of the contest, but to improve compositional balance.
If the title was "Flower" or whatever - this would've been a "part". When you named it "stamen", actualy we can see the whole stamen, not its part. But on the other hand I know, the topic wasn't described clearly :) The colours and composition is good. Maybe a bit tooo much blur in the background, but I'm not sure. 6.
