Finished painting my ugnaughts, and also found some old WotC minis online to repaint as custom junk droids. The droids especially were a lot of fun - tried to go crazy with weathering and ugly color combinations and stuff.
I found concept art and movie stills to use as a starting point for most of them - the green ugnaught is based off a few illustrations from FFG and elsewhere; the blue ugnaught is based off some ugnaughts Leia talks to in the movie; the astromechs are based off a few different cards from IA and X-wing, with a lot of liberties taken; and the Gonk is based off movie stills from Force Awakens and Rogue One.
Overall they were a lot of fun to paint, and I think they'll look good on the table even if they aren't the most useful for actually winning.
