I was sort of artistically inclined at a young age, so I didn't necessarily need to learn to draw...
But here's what really elevated my drawing skills: I drew other people's stuff.
Seriously. It sounds dumb but nothing makes you think about the process of drawing than replicating someone else's working and asking "How did they achieve that line? How did they achieve that kind of shading?"
For me it was Dragon Ball Z. I spent a good two years drawing DBZ characters. The eyes and eyebrows in particular (because they're so central to the character design) but also hair, shoulders....I knew enough to know I didn't want to learn how to draw anime musculature.
Doing that really opened my eyes to the process of design, how highly intentional somethings are. It taught me about how to work with perspective in a way vanilla art classes couldn't, because I cared a lot about the material and that helped the lessons sink in.
So my advice would be to find some art you really admire and start copying it. Not, like, tracing, that's worthless. I mean free hand. It will be terrible at first, be assured of that. But nothing worth doing comes easily. If people say you have a problem with female body shapes, go find some art of the female body you like and replicate it. Just draw it at first, don't worry about how accurate it is. When you're done, do a side-by-side comparison. See where your proportions are off, where your lines don't match, things like that, then repeat the process.
Another exercise that's very helpful (although it doesn't seem so at first) is drawing something you're looking at without ever looking at the page or lifting your utensil. Whatever you will do will look fucked up, but that's not the point of the exercise. The point of it is to get your hand and mind working as a team, building up those mental pathways and muscle memory, so your hand learns to starts creating what you see in your mind.
Once you have lines, perspective and proportions down, the rest kind of falls into place.
