Hey Lukas, I took this course with CGMA https://www.cgmasteracademy.com/courses/115-key-frame-illustration-for-production/ that was heavily blender and paint over-focused. It was intense! I would also suggest tutorials by Jama Jurabaev, he does a lot with Blender https://gumroad.com/jamajurabaev?query=blender&sort=newest

Hey there! I just wanted to add on what was already said  3D is a very big world, and while no doubt that thier are good and elabroate tutorials out there, Ive always felt even following them along will only get you so far.  So Id like to propose an idea. Follow your tutorials until you feel you're at a stage of some comfort with the fundementals of 3D, and then think of something you want to be able to do. Have a clear idea for a project. You can even get a little ambitious and I would really encourage that! And then, make a start! You'll bump into gaps and problems that will force you to ask questions and seek solutions individually, and it will make for an engaging learning experience with good reward in the end. There will be mistakes, struggles, and you may even not reach the outcome you wished for, but you will have a learnt a lot and gained dexterity with the tools. that on its own builds confidence for the next project :) , so long as you keep persisting! This is how I learnt most of my software and its just what's worked out for me the most. but by all means, follow with what makes the most sense to you Anyways, hope this was helpful in some way!
