The yellow flower really grabs your eye in this photo. It might have helped to increase the saturation a little here and maybe crop out those legs at the back.
nice subjects! But I think that it would have made a stronger impression with a different crop or framing. Maybe only having the pink and the yellow roses in the frame would have worked best, so that the other distracting objects (like the people and buckets) are cut out.
for some reason the photo overall looks a bit dull. i think i would have cropped tighter and raised the color saturation levels a bit. the focus also seems a little soft . . .
