Just tossing in a self-portrait I did for class this week.
I sketched with ebony pencil and did details with a black ball-point pen. Cross-hatching shading obviously. Whole thing took about 2-2 1/2 hours. It was a pain trying to get the mirror set up right, and having the drawing board steady enough to draw (I ended up leaning it against a coat rack). I'm looking a bit wide-eyed to the left because that's where the mirror was. Only a few proportion mistakes here and there, but otherwise I'd deem it successful.
