|Greetings from the Critique Club!
Nice vivid coloring in the flower. Background is a bit busy and distracting. I like the angle, it's a bit different than a plain old straight flower, but overall the photo still doesn't have a lot of "wow" to bump up the score.
As I mentioned in my first impression, I like the angle (though some folks aren't such a big fan of that), and the background is a bit busy for me. I like the bokeh you got from the ground, but I find the blues and oranges (people?) a bit unnatural. I also can't quite figure out what the blue-green thing is on the stem of the flower... a ribbon? My suggestions would have been to shoot from a slightly higher angle to avoid getting the people in the background, or to maybe have cropped a bit more from the bottom and right so that the flower itself isn't so centered.
Looks like you had some nice lighting here with the flower petals getting the majority of it. You handled it nicely, with only a few tiny areas of the white being blown out. Focus seems sharp on the flower as it should be and the dof is well done.
Not sure what post processing went into this shot since you made no mention of it in your Photographer's Comments. Perhaps a slightly different crop would have helped to not only remove some of the busy background, but also would have given us more of a look at the interesting details of the flower itself. Also, a slight run through the USM filter might help to sharpen it up a bit.
A nice photo, but in a challenge where voters are looking at hundreds of flowers, to get a higher score you really need to make yours stand out which is why I think your score ended up at a 5.000. Seems that two of the commenters from the voting period also found the background to be a distraction, which is something to keep in mind when framing your picture before you click the shutter.
I hope you found this critique helpful. Please feel free to PM me if you have any questions.
