It took awhile, but I finally finished my FM Millennium Falcon.
http://www.philsmith.us/PhilSmith10.html#Falcon It's built mostly out of the box, though I added PE grills and landing gear baffles (or whatever those are), bought from the Starship Modeler Store. I also separated the engine panels at the rear, which look like they operate independently.
I added a few bits of greebly to the aft end, using a photo of the engine area I happened to have. I painted the thing 1:1 Reefer White/Grime, then used the kit decals for the various color panels as I was a bit lazy and did not want to paint those. I was really happy with these decals, and it was fun to weather them down. Most folks leave it at that, but the instrument/machinery bays have lots of neat little things in them screaming for special attention, so I added color in each.
I really didn't try to be as accurate to the film as possible, especially since the various miniatures of the MF differ anyway. I just wanted to have fun and I did. On reflection, I should not have used the engine grill. I think it looks stupid, and I really can't see the cool row of engine nozzles I labored on. What a shame.
