I can see what prompted you to treat this image in this way. Just toying with an idea: crop 10% off the right, 20% off the left and 5% off the bottom. Bit of a 'buzz-cut' approach, I know. If you have PS, try this sharpening technique, which might need tweaking, but works well in similar circumstances.
I really like this image. The PoP of red is really nice.
I can see what revenant is saying about the cropping, it would change the capture. Depending upon how you cropped it and where the rose ended up you would have an entirely new picture.
