Well Dame I thought said she liked your characters over in the interest thread, but she'll let you know here again I imagine since you're not sure.  I don't see why you wouldn't be though.  As for your ladies, honestly non benders interest me more since they're harder to RP, yet they're important to the world, more so than benders in some ways.  We might have powers, but we have to train pretty extensively just to have a chance against others like us, where we could be studying other subjects lol.  Sure, there's nothing saying we can't be into engineering or some other science or fine art or whatever, but generally speaking, benders aren't known for their creative thinking outside of their bending and fighting.  The point I'm trying to make, very badly, is that without non benders like Kenna, Asami, etc, we might still be living in the dark ages lol.
