I love that door gunner. I'm going to have to borrow that bit of inspiration. I think I may add a kama to mine, and maybe some web gear so he can be suspended from the custom gunship I'm working on.
I agree that the "Slice" GI Joe body makes a great SW body. I have a few of those I may use for Mandalorians or other Mercs.
Also, don't downplay your early work, there's some really great stuff there! I'd seen some of those before but never realized they were yours. I'm especially fond of that black and maroon battle droid. Nice job!
I'm dying to know where the shoulder gear for your green clone came from. It looks familiar, but I can't place it...
