I would not show the second eye, as that is what the originals look like.
I like the covers, but for
TPM, definitely keep Darth Maul, but I would use a Naboo starfighter or maybe the queen’s ship. (EDIT) now that I think about it, maybe use Darth Maul’s ship. One of the three is fine.
AOTC, I would keep Fett, but I would use the battle of Geonosis to match the Hoth battle on TESB.
ROTS, I would use the Emperor or maybe even Anakin for the face, and I would keep the lightsaber fight between Anakin and Obi-wan, just like the ROTJ original with Vader and Luke.
This way, the themes match.
