More importantly. Reading what you wrote, it very much feels like you're not putting the elements you learned into practice.
Do a finished piece. You have to apply the fundies and the studies you make to something you intend to complete, to "put it into practice" and assimilate it properly. It'll also clearly define the areas in which you're lacking so you may do more precise studies after it.
Finished pieces, anon. Regularly. They're more important than all the studies in the world. Do you think Michelangelo carved 1000 stone cubes, 1000 more marble arms and legs and then popped the Pieta out of his ass? Of course not. You won't progress if don't do finished pieces.
