I tend to think of Trandoshans as being built like athletes, so long legs work for me. He looks pretty dang menacing (and I think I might lift your recipe...) I also really dig the inclusion of some brighter colors here. *Very* nice work.
The Ithorian is, quite simply, perfect in terms of overall look and execution of soft goods. Combining the cloth inner robe with a beautifully painted outer cloak just makes him pop off the screen. And the paintjob on the skin makes him look very distinct from the Hammerhead we already know. In a perfect world he might have sleeves, but that's me being unfairly picky. Excellent figure.
The astromech looks sharp. I like the color choices a lot. He would make a nice addition to EE's exclusive sets. The only gripe I have - and it's endemic to astromech customs - is that you can usually tell when one's custom painted vs. factory painted.
Very nice work all around!
