Self portrait with hat...

Although I like this as a drawing I'm not sure how good a likeness it is... I wanted to pose with hat and was tilting my head up and consequently it doesn't look like what I see in the mirror but I guess we are all made up of many different views.
I laid a graphite ground first on cartridge paper, sketched very lightly the key boundaries of nose / eyes / chin and top of head etc and then rubbed out the highlights and worked up the darks and just carried on doing that...
