Nice customs JediStyle!
Poe Tranel - I love the unique paint apps, they turned out great. The belted holster is a nice touch, it's cool and you don't really see it that often. The Master Chief helmet rules!

Republic Commando - I like the accessories and that he's bridging the Mark 1 and Mark 2 armor. I think maybe some sort of gear (antenna/head lamp/something else) would make him stand out a bit more.
Dun Ruuko - Great custom here! Now I know what to do with all of those Cloud Car Pilots I bought!

The Obi-Wan head doesn't even remind me of Obi-Wan, I'm not sure what it is about the figure, but it works!
Gada Ponar - Very cool, we don't see enough Aqualish customs! (I've never done one). I like the parts choices too.
