I think the art's great, really charming, and the black and white fits it so well, nothing boring about it
a lot of the jokes land for me, but even the ones that don't, don't detract from the story
I also have to say I really admired your backgrounds, you mentioned they took you a long time, but they were definitely worth it, they did so much for your world/setting
the only critic I have is about your storyboarding, sometimes the actions are a little unclear, or the panels could be sequenced better, it was nothing major though, a lot of it was solid, it's just something I noticed from time to time
Spoiler
'Rat Surprise! 01' is the only major instance, it was unclear to me he turned into garbage (what a twist btw) until I looked at it a few times.
excited to see what comes of the revitalisation
