How are you using your computer right now then? I added more to my previous post about the CGI buildings.

i'm not. i've commandeered my wifes netbook. I grabbed the pic from my external USB drive that contains the backup of the finished ESB:R shots.

I did tweak some of the CG shots in ANH:R. the dewbacks had a green tint in the shadowed areas so i fixed this to match the real life shadows. A lot of the time the old CG does have a strange coloured tint to the shaded areas so fixing this does go some way to making then blend better.
