No problem~ It's not just Lo-Fi Room that's done on paper, I do most art/illustration work like that. I struggle to get nice lines with a tablet, but adding colour needs less control so I can do that with the tablet pretty easily. But I think for convenience doing everything digitally would probably be better, especially for animation or if you need to make a lot of changes to the design.
Here are some of the Lo-Fi Room drawings on paper, if you're interested: https://www.instagram.com/p/CCCorGLHNn5/
Good luck with drawing! I'd say the main thing is just to draw often and experiment to try and find a style and workflow that you're happy with, but I think it takes time to figure something out that works well for you.
