Great shot, I like the simple composition a lot and the shallow depth of field makes the image very beautiful. I find myself in agreement with some other comments that a bit more light would have been nice. I also find it a bit distracting that some of the colors in the flowers turned out much different than others. Overall a really nice shot, take care and keep shooting!
Lovely colors and tones. I like the focus depth, it just seems to add another dimension to the photograph. The lighting is interesting too, and I believe it has worked well, with the central light source pointed to the center of the photo, fading out toward the edges. Nice job
