The colors in the flower are very nice. I would like to see the top flower more in focus. I don't think the second flower enhances the subject; however, a third flower to fill the upper right area might have worked. Compositionally, subjects are better represented in odd numbers - for images this size, 1 or 3 seems best.
What strong colour! Well selected background. Angle feels a little too elevated to me though I appreciate that's what allows us to see the central circle of the flowers. I think I'd like DOF to be even shallower so that the second flower were even further out of focus. Nice composition, cropped a little tight at the lower edge (the flower feels too close to edge of frame there for me).
I do like the rich colors and contrast, but the background is very noisy. DOF works well, but a touch more on the front flower to make it appear a bit sharper.
This looks a bit over processed in edit. The detail of the petals is gone, and the color is quite flat. You have a nice composition and good background though. 5
