It looks like you tried to put lights from the bottom to give some dynamic effect but I think a reflector from top would helped you to not have dark flower but a bit boosted light from bottom and reflection from top.
I personally find the muted color of the flowers to detract from the shot. Perhaps if there was more contrast between the flowers and the background it would work better (but hard to do with basic editing rules). The daisy in the far left corner which is smaller and more closed seems to unbalance the shot a bit for me, as does the button on the background material.
Great lighting on the daisies! They seem a bit out of focus though, I don't quite understand the significance of the jeans background! But overall something about the shot just makes it work well! It could be the symmetry of the stitching on the jeans or the way flowers are placed! - 7
