The pop-up flash is pretty small and directly on the lens axis. It makes the shadows appear rather dulll and uninteresting. You could try cutting a "tail" on a sheet of white typing paper and taping the tail to the pentaprism of your camera,and then rolling the paper out and around the front of the flash,and then taping the other end to the camera, where the first piece was taped down, thus creating a sport of paper "pipe", which will diffuse the flash and make it effective much lager when used at flower close-up distances. It'll look better than the undiffused flash ion floral closeups, and this costs like 3 cents for the sheet of typing paper and two pieces of cellophane tape.
