First of all I really admire the colors that you manage to capture, they are truly marvelous. I like the composition, but I would like to recommend not to crop the flower. It seems like the photo, the story that it tries to deliver is incomplete.But it all depends of your style of photography. The dof is soft and gentle it gives you an alternate point of view immediately. I would also like to recommend a square crop. In that way the color of the flower will be in greater contrast with the background. Hope that my opinion was somewhat helpful and again, great colors!
