I like that Freya's eyes vary to show that she's thinking and feeling emotions. But sometimes when I'm caught up in the scene, I get distracted when the facial expression changes because the changes flash onto the face. I know it's kind of late to suggest this, but I just realized that there would be a huge payoff for creating your eyes (except maybe the irises) as vectors in anime studio. They could look exactly like your current eyes, and blend seamlessly with your artwork, but you'd have a ton of control over them.
These are obviously not the same kind of eyes, but it shows how stylized elements of your eyes can be reproduced using AS vectors. (My setup here is not ideal, though.) With AS vectors you can use masking to move the iris around, but still keep it inside the eyeball. You could also smoothly animate from one expression to the next. You could even put the gray shadow as a sheer layer over the top of the iris so that no matter where you move the iris, you still have that little shadow placed correctly. And if your eye animation was done with actions, you could reuse it over and over again.

Another thing about the eyes is that the wider eye position doesn't look right to me. The eyes appear to be bulging out of the sockets when the shadows disappear.
Anyway, if you experiment with AS vector eyes, I think you'll really like them. But I know you've already made a bunch of scenes and you're moving along in your project. :D This new scene is great. Oh! An idea for the zombie-demon guys is that you could make the fog layered with greater opacity. Then the guys in the back would hardly be visible and guys in the front would be more visible. It would give it a sort of Kurosawa vibe. But it also works well the way you have it. :D
