Opal for October

I'm late posting this, but that's okay! My birthstone is the lovely opal and I wanted to recreate the design on my nails. How did it turn out? I say for a first attempt is was okay.

My only complaint is that the flakies are so hard to photograph! Hopefully you can see the iridescent rainbow shimmer to it.
Colors used are China Glaze's Rainbow as the base and Color Club's Snow Flakes as the flakies.
