I finally got some more assets in there an optimized the billboard animation. The animation really didn't need as many frames as it had. Also, I was able to limit the colors to save on file sizes. The highest quality art is really only necessary on the frames that are stopped on. The transitional frames have really been pared back as far as size. All in all, I was able to shave 3 megs worth of memory off of the file.
I might go back and change (or possibly remove) the camera move altogether. We'll have to see.
