It's a lovely composition. It does need sharpening and a touch of contrast will give it more separation from the background.
The one thing that is distracting is the white column directly below the second last blossom and can be cloned out.
Another option is to crop the bottom and right borders to half the distance to the flowers that they are at present. It increases the impact, as the current border is roughly the same distance to the flowers from both sides, which tends to centralize the subject and take something away from the graceful curving stem.
