I'm usually not a fan of flower photos, but this one caught my eye because of it tonal range and capture. Very nice job catching the hues in this pink.
I really like this shot and the DOF. I agree with the other comments on the border and soft focus. The copyright seems a little big also and takes some away from this beautiful image.
Nice DOF though a fraction soft as stated! I'd probably work the sats a little just to bring those colours right out. For a change I actually like the border here too though I think it should be a little thinner. It does compliment it. Well done Katherine!
Nicely composed although I feel that the image is a bit soft. The frame is a bit distracting but maybe that's just my own personal taste. I prefer the frame with no gradient blend to it. There is visible noise in this image as well. Maybe I would bump up your levels or curves to bring out the color of this beauty.
