I'd go for the jacket version, possibly using Darth Parametrics idea. And maybe give one color variant the detailed flight suit. But I'd stay away from Greedos jacket and go for something less unique.
Also, maybe you could tweak the skin details slightly. They look good, but also somewhat disconnected from the skin texture, like they're just pasted on top of the base texture. I have no idea how to integrate them better, but if you'd manage, it'd improve the Rodians even more
