I was watching Harmy's Despecialized Edition of ESB, and I just noticed that Chewie should be repositioned in his first appearance (when Han has just returned to base and shouts "Chewie, Chewie!").

In the wide shot of him welding, Chewie is facing the cockpit. But in the immediate next shot (and subsequent ones), he's sitting with his back turned towards it. Easiest solution would be to flip him in the wide shot.

Perhaps this has already been addressed/confirmed, but I only just noticed :)
