Pretty shot of the flowers. A little more noise than I would like to see. Certainly meets the challenge, but not in a particularly creative or out of the ordinary way.
This image has decent color contrast and composed well for the angle from which it is taken. Overall this is not a bad picture.
However, this would be more interesting if the flowers were taken from the side rather than from above. From above gives it more of a snapshot quality. It has background noise that should be removed. If you shot with a little more DOF the lower left flower would be in sharp focus. But if you have to make a choice then the closest flower to the camera is best to have in sharper focus rather than the stem just behind the flowers. Judicious use of dodge and burn would add more contrast and depth to the image which would make it more dramatic and interesting for the viewer.
The image, "Complements", in this challenge is a great example to learn from.
I like the contrast and composition here. There is a bit of grain/noisy that I am seeing, though. It may be my monitor, but it reminds of what my shots look like when I underexpose too much and try to fix it with post-processing.
