Beautiful colors and softness. I think the framing is a bit "off" but I can't really explain what I would do differently...irises are so oddly shaped that it's difficult to frame a shot of them that "works." The light band on the left side is distracting. Good luck in the challenge! :)
Nice color contrasts. It feels off balanced to me though. Perhaps croping a bit more on the left, or leaving a bit more on the right to make it more symmetrical.

Beautiful lighting and sharp focus. My eye is drawn to the white streak at left which detracts a bit from focal point.
