|Greetings from the Critique Club!
I see that I'm one of your 8s, I felt you deserved some extra kudos for entering a flower macro in a challenge dominated by things much bigger than flowers :-) Good comp and lighting, you used HDR to good effect and the b/w works surprisingly well. I would be a little careful in your post work, though, I can see sharpening 'jaggies' and those will cost you. In this case the effect around the droplets especially gives them a bit of a plasticky feel.
Denoise itself can do sharpening on its own, so if you have the original image, maybe just play with a little and just leave out the sharpening. Or do as you did already, but fade back the sharpening to about 50% and see what you think.
Hope this helps
