Thanks so much for the clip Ady; it was a very welcome surprise. The colours are gorgeous -- I love seeing Yoda's skin looking the way I remember it as a kid. I also thought your subtle tweaks to Yoda's mouth as he speaks were perfect.
I hate giving criticism on such terrific work, especially when I can't do anything approaching that level of quality myself, however there were two things I wanted to suggest:
1) When Yoda says, "Look at me: judge me by my size do you?", I notice you now have his eyes shift to keep his focus on Luke beginning with the word "judge." However, I think Yoda should start to shift his gaze earlier, right from the beginning of "Look at me." Currently, he appears to be looking off into space for a few moments.
2) As someone else suggested, is it possible to have the X-wing begin to sink/bubble/make noise the moment R2 first turns to look at it? I don't know if it would be possible, but it would help explain why R2 turns around, and it would eliminate what currently seems like an unrealistically fast rate for the ship to sink.
As for Needa's shuttle, I think it's absolutely perfect as is.
