I like it too Orange... My only critique really is changing up the "fingers". I've always hoped for a keldor lacking the weird finger covers Koon wears since they appear to serve no purpose than decoration or something on him, unlike the mask of course. Of course though, that'd be tricky to remove that and have it look right so I can see not doing it, but it'd be a nice way to really separate the parts from Plo Koon.
I'm into seeing weird aliens too, that aren't as common throughout the Saga, get a random schmuck type of character.
The parts really blended well there. They're recognizable, but they're really plain/simple, but still add some little details like padding and pockets taht make them look sci-fi and functional.
