|Critique Club Review:
I read your comments twice, before the word petals sank into my brain. Up to that point I had no clue what this was. I had several theories, and none of them were close.
You've met the challenge well, and color, saturation, hue, brightness, and contrast are all rendered well.
The darks spots do distract, as you've noted. Macro doesn't leave much room for problems.
Focus and depth of field are very well done.
The curves as the expand out from the center are cut off, and keep guiding the eye out of the frame. I would have liked it better, had there been a way to keep them intact. Also I find myself wishing for a little more drama in the color.
Very nice photo, and one that holds the viewers interest as they try to figure out what this is.
