WOW! I love this shot, when I scroll up and down over the shot I get a really cool optical effect, LOL! :)
This is a wonderful high contrast shot but I'm betting it didn't do as well as you would have liked for a couple of reasons.
One, lack of focus, it seems soft or slightly out of focus. On a shot like this I like to see sharp, clear edges and lots of details.
Second, the cropping could be done just a bit differently. Maybe set it up so the petals on the bottom are just like the top, right out or in the corners. The colors are great, maybe just a bit over saturated but they do provide wonderful contrast.
