Wow, this was good stuff. Fantastic expressions! I was going to give some minor criticism about how it looks like it was rendered in Source Filmmaker, but it turns out it WAS rendered in Source Filmmaker. It also apparently came out in 2016 according to the description, so any critiques now would be pointless. Maybe if you do bring this little dude back, do it in a (mostly) photoreal renderer like Cycles, Arnold or VRay.
