Hi! Looks very cool! Try to use ezgif.com to optimize gifs. One hour playing around with optimization settings once and you will have a good preset for future gifs.
Also, its very hard to look on gifs. I dare you to make things on gifs slide in forward direction, then freeze for few frames and then return back.
If you need, i can make a video «how to». Thank you for attention and I'm going to see another masterpieces of your work ))
P.S. ...aaaah the mood of Hayao Miyazaki's legendary anime drawings on these background pictures...
