I like the color, the profusion of colors, and the subtle diagonal from lower left to upper right. It falls between a composition with a clear point or points of interest and a flatter composition where points of interest fill the frame.
The fairly wide aperture is essential to the image, I like the colours. Whilst I do not think the blossom is overexposed I would consider lowering the brightness of some of the brighter blooms.
Quite an impressive mass of flowers! I like the sharpness of the flowers in the center of the image and how they are nicely separated from those in the background. I think the image would be stronger if the OOF clump in the LL foreground could have also been sharp (probably would have required a different camera positioning and maybe a different f/stop) as I find that blurred group of flowers a bit distracting.
