Hi Brian,
Not really, size and color not as dominant as the dark, sharp other elements. A square crop would help bring it more to the forefront of your composition.
I agree a square crop might work well compositionally and it would remove the bright area on the leaf by the left of the frame and the brown leaf.
While cropping you might also see if you can reduce the brightness on the leaf in the lower right corner, perhaps?

My eyes immediately fall into the dark area between the lovely lush green leaves so I'm left feeling that the crop Rufus suggests may be a better presentation of the flower. Did you find it hard to let go of the green leaves? All too often I find myself excessively attached to elements of a photo that weaken the overall visual impact .....but darn I like those other bits and want to keep them!
Brian,
The square crop is better than your original but your 16 x 9 is the best one so far.
Brian - unless you are printing and are working to a specific paper and / or frame size, there are no constraints on how you crop; square, almost square, etc. You have total freedom to present the shot in the best framing for that individual shot.
Another direction to go with the crops would be in vertical / portrait orientation. The flower is taller than it is wide, so this would be a natural direction to try.
