Lovely photo. I love the range of colors in the photo overall. They blend together from the soft focus and DOF to make them pretty and not distracting. The red of the flowers stands out again the cooler tones of the background, so the eye is automatically drawn to the subject. The only thing I would have personally considered doing is cropping the photo slightly on the right to bring the flowers a bit closer to the center of the photo. I think the rule of thirds would be better applied that way and benefit the photo as a whole. Right now it seems like the flowers are being shuffled to the very side of the photo, which makes my eye want to wander away from it a little bit. You might like it better the way it is, however. Rules are meant to be broken, yes? I love it either way.
