These are pretty cool, I thought the face bandannas designed to look like the helmets was a clever little idea.
Obi Wan wasn't really recognizable at first, due to his duster's color, but I'm guessing it's a bad picture. The description says "I kept the brown and tan color scheme.", but it looks black and gray in the picture.
Chewbacca is a tad too muscular, he looks more like a certain Cimmerian Barbarian, than a native american, or indeed, Chewbacca.
But, having said that, the Stormtrooper looks ace, and so does Boba Fett and Vader.
