What struck me first about this image was how rich the reds are. The droplets look like tiny diamonds on the petals. I really appreciate the depth of field here, too. I like how it's different than many shots because here the background isn't what's blurred out. The foreground's droplets are blurred out and then as you go farther back it gets clearer.
I also really like how you did this so well we can actually see the texture of the rose petals. I can see every ripple and line in them. I'm not sure I've ever seen so much detail in a flower photograph before! The lighting is superb as well.
You did a very nice job with this shot. It's very beautiful.
