No way man, your faces are improving a lot! I'm eager to see how you find the measuring technique with them. Avoid using it as a crutch if you can, but definitely use it to learn.
Given you've been drawing some expressions lately, and you're learning to draw the face in general, I recommend checking out the Artist's Complete Guide to Facial Expression by Gary Faigin. It goes into awesome detail about the eye (very subtle things can change the expression of the eye, but in a reliable way that's the same for everyone), obviously a lot on facial muscles and which are activated for which facial expression, and its own way of constructing heads (which I had a play with last year here, and found useful). Really I'm not sure why this book isn't recommended more often in these forums. It helps you actually understand exactly how much to cover the iris/pupil with the eyelids, why and when.
