What I do, I personally learn best from copying drawings. Usually, I watch tutorials online, and slow it down as much as it can go, then follow the artist's marks step by step. I think attempting to copy an artist's marks helps you understand why they use such marks, and how you can apply them. For example, while watching someone draw legs, I noticed that the artist slowed down near the knee, and used a quick stroke to finish drawing the leg. Idk if this is helpful, and I know this shoots off on a different topic, but this is my general advice! :)
