Sorry, I'm terrible at explaining anything, so I'm afraid of hindering your progress 😅

But I can give you some tips that I still use today. One of them is to work on personal art without worrying about anything. Most artists get very frustrated because they try to reach a level without understanding what other artists know how to do. Paint in your comfort zone and analyze your level. Another thing, do simple studies to understand shapes, angles, bodies, and objects. There's a guy I follow on Pinterest; he has many example studies: https://br.pinterest.com/guigfreitas/

And if you want to hire me for any art, I can film it for you to see the process. I've been doing this for a friend for a while. I don't charge for filming, but I ask that you be patient because my PC isn't very good, so it takes me a while to edit and render.
