Warmups, listed from first drawn.
Your figure drawing is amazing! Great proportions and shading. It looks like your facial drawing is lagging, though. I can tell that it wasn't your focus for these, but the faces look quite stiff and flat in addition to just sketchy.
You are so spot on. I tend to lazy my way through faces because they are a struggle for me, especially when under a time constraint! I'm going to be pushing my focus to them more as I go on.
