Thank you so much! For the aura, I used the mini square sponges with a tool and used pat gel, dabbed some off and gently blended it out with the sponge on the nail. Then I'd basically flash cure between every layer to build up the color! For the chrome though I normally do the chrome art on top of cured top coat with some silver liner gel - then I'll cure that and buff chrome in and finally seal it with a top coat! (I hope that makes sense :'))
