Even looking at your studies, I would still say line quality is a big concern.

"Hairy lines" are a thing that I struggled with myself for a very long time.
A general rule of thumb is that it is better to use thicker brushes for larger shapes and proportions and only to start using smaller brushes for details.

Example of what I mean. Me from now vs me from when I was just starting to really draw.

You don't have to use one brush for everything, and you're not supposed to.
