As we only have two entries so far, I'm going to give Zach some critique now, in case he wants to post another attempt.

The concept is great, but I personally dislike when not a single flower is fully in focus. The top two have their center bits OOF. The one below is OOF before we get to the ring of petals. I find both distracting. You need a slightly smaller aperture (lower f number) to make this one work.
