Looking back at this page, I wonder if I made a mistake in not showing more clearly where Millie's location was in proximity to the other characters. I felt like it must be obvious, both in context and from where Loona's looking, that she's at Blitzo's office door. But it also kind of feels like she's popped out of nowhere.
It might've been better to have a more zoomed out shot, where we see multiple characters at once, so we can actually see how Millie is able to see Moxxie but Blitzo can't.
