For the closing, I’m going to redo the credits over imagery from each episode’s episode gallery / BTS gallery on StarWars.com. This’ll be much more like Mandalorian, which has those lovely bits of art.
This will be over particularly dark, ponderous music - I want us to take a beat after each episode and really digest it. I think the best track for this might be the prelude to Order 66 music which slowly builds throughout the third episode of the final arc. This would serve us nicely because it’s dark and ominous - welcome since we know the inevitable conclusion of the Clone Wars and mentally it draws us toward that end…
I’m a big big fan of this, music is the way I connect to tv shows and movies, especially Star Wars. Having that subtle change in the intro and outro for each episode would help to maintain the darker atmosphere provided by the inevitability of ROTS and Order 66. I don’t know if you’re asking for suggestions on tracks to use, but there were a couple I found that might fit! They sound similar to the one you posted in terms of something more low key and emotional:
