Too OOF, overall pretty flat. Needs some sharpness and some pizzazz. Reshot with very careful focus, steadiness, and stronger light and it would be very nice.
I love frangipani flowers .. great subjects for a photograph. However, this image suffers as the pink flower is not in focus and I find its placement in the center of the image rather "static". I am wondering how you achieved the selective desaturation in basic editing since the background flowers are presumably the same color as the central one?
Too soft focused and the colors too muted. I expect to see many flowers in a PINK challenge, so in order to catch the voters eye and stand out from the others you would need something very extraordinary. Sorry, but to me this lacks the WOW
