Wow. I'm still trying to figure out what to classify this as. It looks like it could be technically but not stereotypically steam punk, but I'm guessing more ww2 or 1920's era? The imagination it spawns is breath taking, though. The red balloons make me think Asian (*cough cough or fire nation cough cough), but their clothes don't.
Fire Nationy, NOT Flaming Nation, FIRE. I think we gotta specify. I may not have a problem with it, but that don't mean I wanna get labeled or absorbed in something I'm not. "Hey, look. It's the flaming nation empire!" *sigh* Me, or one of your characters: "Even if we conquer them, they won't take us seriously."
