Oooh..Lovely shot. I would have expanded the shot more if you wanted to use that border. By that, I maean I would have pushed the border out further and perhaps had the portion of the photo outside the border to be slightly blurred or something. Just amatter of style and presentation choice. The photo itself I really like. It has a very simple, clean feel to it.
I'm not a big fan of floral shots, mostly because I find it is just too easy to get an attractive photo of a pretty flower, so when I vote on one, there has to be something well done to make it stand out to me. The composition is spot-on rule of thirds and leads my eye nicely through the frame. The treatment and light is nice, being just soft enough to be pleasing, but still has lots of details showing. (I love to see lots of fine detail). The border didn't have much effect on me one way or another, but it probably does add a nice touch. I think the objection to it may be that it overlays with the actual subject matter. I really can't find anything to nitpick about here, and I gave this a very high vote.
I'm not a big fan of those frames that doesn't "end" the photo. It draws my attention outside instead of inside the frame. Apart from that, composition, pre and post production and toning is f'ing awesome!
Lovely light, very nicely balanced composition. I like that the background is not pure black - there's a hint of the leaves behind, and I really like how the center is just becoming visible - you've caught that stage just before the bloom is completely open. Focus is good, though the OOF foreward most leaf may put off some. And I'd wager your score would be higher without the inner border - some people really don't like borders, especially if there's more to them than a simple black line, and in this shot, the blur is not entirely obvious unless you relaly look for it. The tone is warm - reminiscent of low morning light.
