It's good to see you back here. The irises, themselves, are beautiful of course, but your image takes them up another notch, at least. I like that it's not obvious that Pixel Bender was used for part of the magic. One of the great things about the image is that the white part of the flowers stands out from the background while the dark part almost recedes into it.
Hey Dave, Very nice. Cool understated filtering. Black BG really makes these flowers pop. I could see just a sliver more on the left, but that's personal preferebce.
