The diner scenes look great, the 3PO shot still looks a bit too green.
It needs a bit of fine tuning, but I think this is much better:
Beautiful!
I like this one a lot better than the one you decided was final. It doesn’t have that “green” feeling your final has, especially near the bottom of C3PO and the “yellow” splotches on the sandcrawler. Here those splotches look like a natural part of aged and rusty metal in sand.
