The rich blue sky looks better, though I understand the reasoning behind having a slightly greenish sky’s on a planet of yellow and orange sand but it’s not a science fiction film so aesthetics are a higher priority. Loved how you have reflipped and reframed Threepio. I noticed this from the original ANH:R but just adding the blue eye light to Artoo makes him more Artoo. Everything looks sharper. The Battle droid cameo is as subtle as it originally was. Hopefully you will manage to sneak at least one Rogue One style Imperial battledroid onto the Death Star.
