It was charming, It was hard tell who was talking since all of them had no mouths.
One way that the ClockCrew gets around that is to make a little wiggling arrow appear over their speakers head for emphasis.
Another way is to add a text box with the name of the character and a portrait in the foreground.
I love the zooming camera effect and different camera angles, it kept it from being too static, and made it more cinematic.
I wouldn’t suggest using Windows movie maker for animations though. It’s not really made for that, believe me I’ve tried too.
There are a handful of free animation softwares out there like Opentoonz, Blender, Wick Editor, and Flipaclip. They all have plenty of tutorials on Youtube to learn them all.
I’d also use more pastels or less saturated colors for the backgrounds as well, looking at a bright neon yellow screen can be hard on the eyes.
I can see you put a lot of effort into this due to the length, that alone is pretty special on here. It’s a pass in my book, good job!
