Technicalities aside, I think it's a very pretty explosion.
From watching videos of real explosions they often eject lots of debris / embers which often travel pretty far. Thats the look I was going for. I would have prefered to have made the trails a bit smokey, but that would increase the already pretty high particle count.
Heres a video showing in part what I based it off.
