Notable improvements and more!
Nice work. You've still got a little way to go, but the stride-hitting is imminent.
I didn't really laugh out loud at anything, but I found several parts to be legitimately funny. There wasn't much dead air at all.
The most noticeable problem at the moment is the backgrounds. They're very stiff and lifeless. I understand the limitations of a weekly cartoon, but I think you can probably do a bit better.
And you got Ed Atlin to do guest voices! Aww.
