I really like how you get the expressions in the eyes, especially in the profiles! And I really like how good these look for just a few days of practice.
Something about the lower parts of the face--jaw, nose, mouth--feels like it's off consistently? It works better for me in the profile images than in the front and 3/4 views. Were I you, I might take some time looking over refs for proportions of that lower half of the jaw, then focus on that area with the next 2m practice?
