I rarely do washes with painting, usually dry brushing works better for me. But what DD said about washes is definitely good advice.
Darth Delicious -
The Trandoshan looks awesome. For the life of me I don't know what you used for the torso, but it looks great. I would really like to be able to make something like that someday.
Also, the kneeling Clone looks freaking awesome.
I also like your Sandtrooper. You may want to paint the eye holes a bit as Hasbro in my opinion left the edges a bit too white, and also the breathing nozzels in the helmet could have a touch of black as well. It's a pain to make these "corrections" on the VOTC Stormtrooper helmet. I've done it on about 20 of them and man it's a pain to do. They still look great without it though.
You've really added a lot to this section; it needed you! And Sith Lord Chaos too!
Also, we might be seeing Owen D. around here soon as well... I don't want to pull anyone away from Scum, but it would be cool to see a few more people active here. You guys have given me, Famine and Dimetrodon new life here.
