I love the light on this floral shot - it shows off the delicate hues of the pinks. I do like the bokeh in the backdrop for those pastel hues of the natural environment complement the flower, but I think that there is too much negative space. I think the composition would be even stronger if you zoomed in closer to the first flower in the foreground such that it now fills a 1/3 of the frame on the left side. The flower in the backdrop would still be in the frame but appear in the far right - and you should not lose those fabulous green/yellow bokeh circles I see in the top part of the composition. Get at a slightly lower angle to shoot up at the flowers so those bokeh circles would then dominate the full backdrop. Just my two cents.
