Two things come to mind Brian.
The bloom is lost in space. Try a tighter crop. (Think this would make it pop)
Maybe just a little to dead centered.

This is probably the one quote I continuously refer people to when they ask me how they could improve their image.
Hi Bri, Mr Picky here,
I'd crop too but only enough to make the foliage less obtrusive. Perhaps like this:
I'm partial to the harmonic mean (Golden Ratio) but others here might like the rose more central or even positioned further out per the 1/3rds rule.
I'd tone down the specular highlights where arrowed. Screenshot is from RawTherapee.
Nice flower, BTW.
+1 to Ted
I like the splotches of water on the leaves. I think you can have equal portions of black and white within a composition and you can definitely have one tone emphasized more than the other. Have fun experimenting.
I agree with what Ted suggested on how to crop the image.
Gardenias do have a marvelous shape which is why I thought of B&W for the shot. Everybody agrees that the crop was a little(?) lose. I could have done more to the highlights than I did.
I usually start in rule of 3, move into fifths for fine tuning, check it out in harmonics and then finally with entered. And then a good old fashioned eye balling. But this tijke in do seem to have missed it.
