Animation itself is okay, if quite slow and a little ... boring? Not much going on. Sound effects are a little bit loud. Choice of music is a bit stale -- overused in videos I've seen on YT, and I'm not sure if it's copyrighted. If it is, that stuff isn't allowed here. It would be a lot better if you had more fitting music actually. The NG audio portal has tons of ambient stuff that might suit your needs, or you could commission an artist.
