Sure Tomek! Sorry for the delay with this reply.

Daniel Scott has an amazing course on Skillshare to cover the basics of After Effects. (https://www.skillshare.com/classes/Adobe-After-Effects-CC-Animated-Infographic-Video-Data-Visualisation./1411469263?via=user-profile)

What I usually do when I want to animate something I don’t know how is to look around for similar tutorials on YouTube and learn the basics to modify and create exactly what I have in mind.
