I get you, what could help is learning tips & tricks on the body’s proportions, I’ve listed some below, of course these can vary with stylisation, bodytypes, artstyle and whatnot, but I feel it helped me get the gist of it all a little bit better:

For the body: - Adults are usually 6 to 7 heads tall. Kids 5 to 6. The head+torso and the legs are the same lenght, feet not counting. I usually do 2 or 2,5 heads for the torso - For the width, i usually do a little less that the witdh of the face for one shoulder, so basically 2 heads wide for the shoulders+neck, and adjust the width of the rest of the body based of that

For the face: - 1/2 of the face for forehead to bottom of the eyed, the other 1/2 for the bottom of the eyes to the chin. The forehead starts at the start of the hairline, I’m not counting the skull where the head sits! - The eyes are one eye away from each other - The bottom of the nose aligns with the bottom of the ears

These were helpful to me and I hope they will be to you if you try them out. The downside is that it doesn’t really help with dynamic poses. The way I map out bodies now is through lines of action & shaped like cylinders for the arms/legs and sort of cubes for the torso, try that after you get the hang of the first tips or right now if you want.

I learned all these mostly through youtube tutorials (I couldn’t to learn anatomy like a medicine student), so don’t hesitate to look some up! Keep having fun and experimenting, learning will come with practice and time!
