I start with Asymptote, a green-to-olive nail polish with a quite fine-grained, mostly scattered holo but with a hint of linear holo in it. The shimmer shifts a bit to light copper, yellow and maybe also some pink. I like it a lot!!
The formula is a bit difficult to handle. It is gooey and must be applied rich and pretty fast, or it will leave bald spots. It will probably be better with practice. Handled like this, two coats are enough. I think you could even get away with one coat if applied very fast and rich.
