Ok - most of these challenges I feel like I stepped up and did a good job...
To be perfectly honest I'm not so happy with this one, but I was too lazy to redo.
If you can't tell, they're fireworks. I started with a black base of Essie Licorice. To create definitive streaks I used OPI Love.Angel.Music.Baby and Konad Silver. For the glitter element I used a combination of microglitter polishes.
Girly Bits Razzle Dazzle is raspberry microglitter, Cique Queen Majesty is purple and blue and Cirque Stella is full of rose gold. This second picture shows it with Essie Matte About You, y'know, just cuz.
