Wow, that's a lot of dirt you had to deal with! I don't envy you that.

If I may, the floor and hallway look dead, suffering from held grain, as if you created a single clean master frame of those areas to replace as much of each dirty frame as possible. The trick is to make several of those, using different source frames to make them, and use a different one each time you paint out a piece of dirt. That way the grain is different for every cleaned frame. I hope this came across constructively! :)

Also, this is the first time I noticed that Hamill looks like he's about to laugh in the last few frames of the shot. LOL
