the colors, especiallyh the superb shite of the flowers, lighting and detail on this are excellent....but it is not a very interesting composition at all, imho.
Good shot and design. Has it been desaturated? Looks a little on the green side, might be natural. But perhaps a little more saturation or yellow in the flowers would punch it up a notch.
Technical: Most all images submitted fit the challenge. This fits well. Exposure composition focus lighting all good. I really like the angle you chose to shoot from.
Personal: I would like a more contrasting background to make the flowers stand out more- I think more color would make this more interesting to look at.
I personally don't care for the angle of this shot, to me it almost looks like two big eyes and a nose (the vase), perhaps it would have worked better from a different perspective.
