Couple of things I thought I'd comment on. The second panel has a couple of experiments in it. The first is perspective, they're supposed to look like they're coming at you as Toph hovers over you. And the asymmetric expression. She's pulling her lip to her left as she gets more and more in to it. I have to admit I wasn't sure quite what to do with Azula, and it kind of just started to look like Toph was starting to dominate, so I lean in to that over the next couple of pages.
