When I look at your trial pieces, I feel like the flower part... the purple part is over worked. The beveling doesn't enhance the fine detail, but rather makes it look somewhat like a scallop edged spoon. Sometimes LESS is more.
I think if you use a hair blade (or several pointy crafters xacto blades taped together) and make deft long cuts so that it looks a lot like hair... and then only do a little beveling around the entire flower (purple) part and the bulbous area, you will be much happier with the results.
