You got something going here. The narrative, voice acting, and simplistic character designs fit the wackiness of this series, so that's a plus. Some things that I found offputting though were the backgrounds and character animations with how the characters suddenly jump from one pose into the next. The dialogue animations too could use a few in-betweens as well to help bring more fluidity to how the characters move. The backgrounds especially could use some touching up as well as some objects like the trees and the camp's buildings appear flat in relation to their surroundings. Some interior shots in the latter half seemed inconsistent compared to the previously hand-drawn backgrounds. Additionally, the intro music, although lighthearted and joyful, felt overwhelming on the ears. Might be how it's mixed, but a lot of the instrumentation sounds like it's having a war with itself. Best to leave some breathing room for other instruments to lead the song to make it a recognizable ditty.
Despite what I said, it's not a bad start! You've pretty much laid out the essentials and have a visual blueprint of what your series will be like. I would heavily suggest adding more frames of animations to character movements and polish the backgrounds to bring more life to things going forward.
