Sounds good enough for spraying acrylics with a cheap spraybooth I think. I don't fully know how bad lacquers actually are for your health so take anything I say about those things with a grain of salt.
I also went through my YT history to find some of the channels I found helpful learning. It's mostly just people going through their build process rather than concrete tutorials, but those were always the most helpful for me because they show how "proper" painting should actually look like. A lot of it isn't actually gunpla, but the process of painting plastic is mostly the same regardless of whether the plastic is shaped like a tank or like a giant robot. Also mostly weathered stuff because that's the kind of thing I like.

Minipainting channels have a lot of useful stuff here. While some of the more advanced minipainting techniques don't carry over, the basics of thinning and applying paint do.
