This is one of my fav types of flowers, the iris. This is an image that would have done very well in the recent "Shallow DOF" challenge. These are difficult to photograph well, and you have it just right with this image.
The DOF is a bit funky. The ultra sharp tip and blurry background is ok, but it seems like the less interesting part of the flower is sharp here. Also, there is a leaf at the bottom center that catches the eye and distracts. I would have cropped it out for this chllenge (Though cloning would be better as to not lose more petal, but not for a basic editing challenge!)
Same as mine (well, very similar!) I like the DOF here, but the yellow parts of petal ended up looking green somehow.At least they do not appear blown.
Good luck!
