I had a lot of fun doing Primitive Star Wars so I'm on the sequel now. In terms of planning out the animation, I've divided the movie into about 8 "chapters," with this being the first. Chapter 2 is almost entirely the battle of Hoth, so that'll be a biggie.
In keeping with my tendency to beat certain jokes into the ground well past the time where they might possibly be funny, I've decided that in this version, tauntauns drop dead with startling regularity, and Luke is constantly getting weirded out by the medical droid.
