definitely a very good shot, the shallow field of focus, combined with the complementary colour combination are what make this shot. they give it the surreal feel, like it is in a world of it's own.

however, there are a few things where this photo could possibly improve. the main thing is exposure. especially the yellow flower that is in focus, it is a tad to dark. compositionally it is the subject of the piece, but the background distracts from it by being brighter and more saturated. the same goes for the white flowers, but since they aren't the subject they are almost a non-issue

those same flowers also have a bit of a blue colour cast, but that actually fits the mood of this shot.

i feel that this shot, with a single masked levels or curve layer for the flower could be a definite but right now, it's almost there, which sadly means it's not there at all
