Honestly best advice I think is spend more time, A lot more time. I first started using blender when I was 12 I’m 15 now and still don’t feel I’m where I want to be with it(great place to start with blender is BornCG tutorials on youtube in my opinion). But in all reality people spend years studying this stuff, you could spend a year easy learning just how to make good animations. I wouldn’t expect to be anywhere in a month your expectations are to high, learning through youtube tutorials is a slow process but as long as you are learning faster then they are updating you’ll get there.
