Blacktober Sketches

Most of my Blacktober energy is going towards making some fanservants/ocs but I still have some time for these experimental sketches. I really want to push myself with these. One of the things that disappoint me the most about my art is its stiffness, which greatly hinders potential expressiveness. I think this ties into a second problem I have, which is I draw extremely slow. The problem probably comes from me getting too caught up in the anatomy and not being looser or freeform with the drawing. These were both made under a time limit so I apologize for any major mistakes but these kinda growing pains are what I gotta do to get better.
