For this one I experimented with overlaying small graphics bit by bit to make a large graphic (highlights for the circular wave) and more tweens used for fading. Things seem pretty choppy atm...
Has a lot of depth to it!
I think the colors you got out of it are awesome. GIF doesn't export your exact target animation milliseconds in most cases. GIF's frame dispose time is in 1/100th of a second increments and milliseconds are, of course, in 1/1000th of a second increments. But the end part where the stuff at the blast site eases in moves quite a bit, so you might need to ease up on how much they change (scale each frame call closer to its predecessor between those ending frames).

Really good job!
