To add a bit on the last dude, about the pacing. Either things could've been slowed down quite a bit, so most shots could linger a little bit, to let the eyes take in what's going on.
Or you could have left out a lot of material, and saved yourself a lot of work, of adding so much content and details that, go unnoticed because it all goes by so fast.
Its most obvious right at the scrolling shots at the lockers.
You have 2 quick scrolling shots, Where you got a total of 19 completely different characters (not as greatly drawn as in the more detailed still frames, but still with a good amount of effort put into them). And they all zoom by in roughly 3 seconds.
All very nicely done, dun get me wrong, it wasn't lost on me because I looked back and paused it to do so. But all of that hard work will go lost on the avarage viewers. Lots of corners you could have cut for yourself, to save a lot of time and hard work, without losing much or any entertainment value.
But don't mind any of that, if all the extra work was fun to do for yourself.
I just can't imagine anything else but a cruel and long grind, to stay producing, to put in that much content, for shuch a ralatively short duration.
But a very respectable choice nonetheless. And way more fun, for the few people, who do stop and pause to look at all dem details ';3
