I finally found the original picture at nailside (which has tons of awesome nail designs by the way), and you can find her instructions here. I'm glad I started on my own because I was a little confused by her instructions anyways, but that's just me. However, I also didn't find the tutorial until I started my own version lol.

Well Whore(der)s, I'm off to slowly attempt to paint my left hand now. Good thing fireworks are erratically shaped.
