These are lacking for multiple reasons. Firstly, 1000 polygons is way too much for five flowers, especially since you'd expect to use several of them. Second, they look more like little pies or buns than flowers.

Make the scattering more random, more diversity to each flower, preferably more depth to them (right now they are very flat). Use a texture which isn't so bland, and perhaps make them a less symmetrical shape.

Already made an updated version months ago, just forgot to upload it.
