So far all of the critiques have addressed post processing and editing. I think the real problem with this photograph occurred before the shutter was pressed. You have a lovely subject here (I love flowers) but I question the camera position which conceals much of the beauty of the flower. A higher angle would have revealed the beautiful centre of the flower and allowed you to eliminate many of the vivid, and distracting, flowers in the background. Depending on how you positioned the camera, the yellow flower would be gone. But I have just done what I often object to - critiqued the picture you didn't take. To salvage this one I would radically crop until the pink blossom covered more than 50% of the image, then I would dodge those very dark flowers in the background until they cease to overpower the subject.
