Hello Yukino. I’d say go small, not big. Even for people who work all the time in 3D, mid to big projects are draining. So start slow and small again, otherwise you run the risk of abandoning the whole thing. I’d go as far as to say not to focus on small things because you have a big scope in mind, I’d say small small, like start watching tutorials again and aim for simple things and as you get more comfortable, you scale up in scope, but slowly. It’s not a race or a competition, so you’ll be ok.
