Nicely composed with a great background.
Since you probably chose f/4.5, you were looking for a narrow DOF evidently. You succeeded; but my own inclination, which is admittedly subjective, would like to see a bit more DOF with the same POF.
A beautiful passion flower, nicely presented. I like the soft feel given by both the background and the out-of focus areas.
I think the DOF would be about perfect for me if the pedals in front were not OOF.
Probably requires a stack to do that.
Love the color and the flower is really nice.
