Portraits in pen and ink

Couple of posts ago, I said I was having fun with pen and ink drawings, and I still am. I've been doing a bunch on portraits with them, and this one turned out particularly well, I thought. The source material is a reference picture at wetcanvas. I drew this on my sketchbook on an XS Pitt artist pen.

All that crosshatching almost drove me crazy tho.
