Let's Get This Firework Started

Seems like these days the only time I draw is when I'm doing a Warframe contest.  This is for the "Not Only Clem" contest featuring Twin Grakatas.  This idea popped up in my head when we were listening to Katy Perry's Firework. Forgot how hard is it to draw, and it's even harder to do WF fanarts when the characters all have really weird anatomy.
