Okay, well... the particles (flame from the exhaust and explosion) were done with Wondertouch's ParticleIllusio, and the starfield was a particle generaed by Apple's Motion
Everything was layered with alpha channels, and I plan on taking out the starfield one day, and for future shots, by removing an alpha layer and animating it all with a star sphere in A:M, then overlaying the Wondertouch particles.
I think the rocket itself could use slightly better lighting, but all in all, I'm pretty proud of my first official posted animation.
