I'm surprised to see that there were four whole idle poses drawn here. Unsurprisingly, the Norah one actually jumpscared me, 'cus I never expect you to draw her; so seeing her in your artstyle's always a pleasant surprise. :3
The thing I like most about all four of these idle poses is that the personality of each character is easy to read by simply glancing at their faces and how they hold their microphones. It serves as a good example of - and a way to practice - strong character design.
(And I'm only now realizing this, but drawing FNF-styled idle poses seems to be a great way to quickly whip up a full-body reference for a character. Might try that myself at some point.)
