Not that anon, but if you're just starting to learn drawing and you're serious about it, drawing from imagination at this point sadly wont result in progress.
Why do I say this?
1. You have not yet learned the fundamentals. (structure, gesture, anatomy, perspective)
2. You have not built up the mental library necessary to depict people without using a reference
Really you're at risk of reinforcing your anatomical mistakes if you consistently keep repeating them for a long enough time.
You'll struggle drawing from imagination since you'll lack the reference point for how those things should look in real life.
I understand you might be doing some practice from reference outside of the thread but it would be cool to see what that looks like for you.
I would recommend practicing construction, line quality and simplifying forms. Practice drawing cubes in perspective. Practice drawing straight lines and round circles with one stroke each.
Practice simplifying the human figure into more easily understandable 3D shapes like spheres, cubes and cylinders.
If you start practicing the fundamentals the right way I promise you you'll see noticeable improvement in even a single week.
