Do you have any rub-ons that are too small or left overs from your other projects that you don't know what to do with them? Why not use it on your flowers. In my recent project, I've used some of my old small rub-ons as flower centers. You could also apply rub-ons on the petals to give the flowers some character. Add more details to it using Dimensional Pearls, Liquid Pearls, Stickles etc. Try it!
