Hey Ken,
My only nit's are minor and an easy fix. I really like your red on red and the fact you chose a nice curve pattern. You should tone down the hot spots on the front petal and I would probably eliminate the BG bright V shape at top right (not with crop but clone and heal).

The image has some pleasant tones and details but there is something missing. Seems too plain for me. Even a little spider or leaf hopper would have made the image.
Hi Ken, I echo Roberts comments - the eye tends to wander around looking for a centre of interest. Including the stamens of the flower would have been beneficial here.
Hey Ken, I love red images as they just scream on the screen. Its not a bad comp, but I think it needs some more flow, and not sure how to help without seeing what other options you had. For me the highlights add a little interest, and cause some breaks in all that red.
