The white in the background really dilutes the attention you really want on your beautiful yellow flowers. Reframing would be one approach to get rid of it, burning a vinette around the edge would be another.
Once you've done that you can push the brightness a little?
I'm going to assume there are ten blossoms there, I can't see them all or differentiate them all from one another so.. benefit of the doubt! Now then I think the coloring is gorgeous, very vivid, love that. The focus is pretty good. I wish it encompassed all of the blossoms rather than mostly the stem/branch portion. Composition is a bit boring. They feel just plopped there in the middle of the scene, nothing too dramatic going for them other than the bright color. Use of natural light is good though and the bokeh affect in the background is excellent. I gave a 6.
