This looks fucking amazing. I love how much work, effort and detail went in the animation and effects.
Only the human looks a bit overanimated and robotic sometimes. But that's just a nitpick.
I see that you use a lot of 3D/rotoscoping techniques, which does make it easier, but I'd be a bit careful animating humans and organic things this way.
The colour palette looks veeery accurate to the way the colours would look in the era you're inspired by.
