I think it might help a little to focus more on clarity in your figures! There's so much focus on surface level rendering -- defining every tiny wrinkle in solid black shadow -- that the figures and faces become difficult to read. There are some figures where I legitimately can't quite tell what's happening; others I can see what they're supposed to be, but it's difficult to make out any expression or details beyond that.
You don't want every single part of the figure to have the same level of complicated rendering -- the over-rendered details covering every inch of the figure make it look more like a pattern of tiny shapes, and then none of those details stand out or have meaning. It might be more effective to pick some parts of the drawing which should have detailed black shapes (for ex: a couple snarls on the muzzle, details on the abs) and then other places which don't need all those details (the cheeks, the chin, the shoulders) and can have larger, simpler black shadows and hilights
