I liked the tricky texturing thing you did with the planets in the opening credits. And animated Carter fits his chair noticably better than animated Kirk did.
While this is a tribute to TAS, we did take MANY opportunities to 'fix' some things that even as a kid I noticed. Like how the rear colored monitors above the stations would change (Like communications..sometimes it would be blue, sometimes orange). Or how people's ranks change mid-episode or even the color of their uniforms. In those areas, everything will be consistent from scene-to-scene.
