Hot Pink Disco Half Moons

Still working on manicures utilizing some sort of sticky paper thing to block one color off before applying another. I'm getting better at keeping the edges neat, but need to work on my patience. I always want to put the stickers and second colors on before the first color's dry! This, I am learning, is a no-no.

This time, I used Julep Rose as a base, and butter LONDON Disco Biscuit as the top color. Disco Biscuit is a cooler hot pink, and it really warms up next to Rose's warmth.

I did this during a mild obsession with Milani's green nail art polish (a.k.a. the only nail art specific polish I own), but my recent acquisition of a double-ended nail art brush/dotting tool should really open up some possibilities in this arena for me. The lady at Sally's told me to use acetone-free nail polish remover to clean it. Do you concur?
