MP-153 Animation

This is my first animation in principle, and my first work in blender too. Yes, I see mistakes and problems in the animation in some moments.... I could probably fix them, but to render one moment for 6 days..... In the next works I will certainly take into account the mistakes made here. And I will also clarify that I did it with long breaks (from July to today), so the quality of animation in the video is proportionally improved! Thank you for any possible criticism or tips for further work on animation in blender
