Self portrait - Structural drawing with optional tone

For my Heads and Hands class, we were given two weeks to draw a self portrait using structural lines. Tone was optional but I ended up toning my hair in WIP 2.

The nose and eyes were adjusted from WIP 1 and I still couldn't get my right eye ( left in image) to look right , the pupil and iris were in tangent with my glasses so it was pretty difficult to determine where the pupil stopped and where the frame of my glasses started. 

I gave it my best and worked on toning the hair, shadows and highlights included. It turned out pretty well in my opinion but I'll have to see how the group critique turns out !
