Hey Sonya! I'm already familiar with AE but I admire the Kurzgesagt channel since years so it was an  obvious choice to at least say hi and create a fun project around here :) I'm teaching After Effects as well here on Skillshare so the class is even more valuable to see your approach. I tihnk you animate wonderfully, was so enjoyable to watch and create :) 

Tried to make a seamless loop with elements flapping and moving. A few of them (the weel and roof) were dragged with puppet pin.

Thanks for the cool tips and sharing some story behind it, I'm flying off with my plane now :)
