was watching ESB last weekend, and remembered some of my qualms with it (in addition to what you have already listed)
1. Fireball when the Probe droid crashes into the planet is either too small or moves too fast to look like the probe.
2. I can't stand how different the new Wampa looks from the old one. I would suggest removing the new Wampa all together.
3. The sound of Luke shutting off his lightsaber right after the Wampa scene, but the lightsaber stays on.
4. When the fallen AT-AT gets blown up, the chunks falling into the snow and the way the snow reacts makes it look lika a minature. Maybe slow the falling chunks part down?
just some suggestions.
