You could do the innermost petals with a 5-petal cutter (or with a cutter that cuts individual petals, I'm just partial to the 5-petal one) and do the outside petals with a larger single-petal cutter. I think the main difference between this flower and a more traditional rose is the way the edges of the petals are shaped - more gently waved than curled back. I'd say that that's what makes it look like a cross between a rose and a gardenia, too. Best of luck with this, by the way. It's a very pretty flower.
