Gale could be any random merchant selling shoes. He looks like no one. Why have concept artists? This character could have been auto-generated.
In fact, all of them could have been autogenerated. Except Lae'zel, but in this case it feels like the 3D artists had trouble translating the concept art into a decent 3D model - or higher ups intervened and messed it all up. There is plenty of concept art around, they can look decent. In this case it looks like they took a basic female head, shrank the nose with proportional editing and enlarged the lips, done. The result looks ridiculous. No nose (or a real gith nose) with a smaller mouth would look way better.
