Comments appreciated, thanks.
I agree with the others, that the composition and lighting are very strong, and, to some degree, I think that the 4th flower is somewhat distracting. Howeever, without it in the picture (if darkened out or cloned out, for example,) the bottom right quadrant of the picture would seem to me to be lacking and therefore assume too much weight in the image.
Since the 4th flower is already blurred, which is fine, you might consider a bit of dodging and burning. Namely, to very subtly and gradually increase the brightness leading to and including the 3 flowers, and slightly and gradually darken to the corners of the image, as in a *mild* vignette. Then, the 4th flower could be carefully darkened just to the point where its tonality "matches the blur" in weight. That way, the eye would be more strongly drawn to the 4 flowers, and the 4th would not distract, but would still make the lower right quadrant a contributing part of the composition.
The curve of the dark leaves sets the main focus on the 3 flowers in an elegant fashion.
I don't know if this helps or not. It's a quick attempt at what I described:
