Love both of the clips. That new Hoth background at the beginning is great and I never noticed how oddly that star destroyer lowers in that establishing shot.

One thing I've wondered and I don't know if it would actually help but have you tried applying a tiny motion blur to the digital mouth enhancements to Yoda? For some reason I think it might help in the same way when they apply it to stop motion nowadays but I'm probably just talking nonsense.

That Bespin sky comparison is fascinating.
