The first one is a beauty. It is a happy iris with nothing to hide. Its beard being the same color as the falls makes the standards more outstanding.... lovely contrast and beautifully soft colors. The next to last one does the opposite with the beard picking up the standards color and intensifying it. Cant tell by the picture but the shoulders may have some of the pink tones also.
The last one is a beauty too. In the shadows its beard looks black and in the light the dark beard has tones from the standards giving it a brass/brown look and sets off the dark color streak running from the beards down the falls. A bit of drama from that one. All have great form and in person it would be very hard to choose only one.
