Clearly, a very DNMC photo. The description implicitly states that your photo was to be in B&W. This happens to be the first 1 I've ever given out. Congratulations :)
Its a nice photo, but this challenge said that the photo MUST be black and white, with no colour allowed. I would have attempted to have a slightly greater depth of field, as even parts of the main flower are soft because of the depth, while the center is very sharp.
This is NOT black and white.. it has COLOR components it it. Please go back and read the description again, it is simple, and straighforward, and says 'take a black and white image'.
Pretty picture otherwise. I would have changed the lighting a bit... and cropped in more on the inner loops.
Description of challenge: "The final photo MUST be in black and white (and the grays in between)."
I've gotta vote you lower because of the color. Bummer... I'm sorry. :(
The full details of the challenge (which I'm sure have been quoted to you by now) specify a black and white photograph. That said, this is a good shot - lovely softness to the blooms. Has just a touch of blue to it - not sure if that's white balance or the environment at the time you shot it.
