I am finally done with this one! I started for almost two weeks ago, after watching this incredible tv-show called "House of cards" with talented mr. Spacey. I haven't drawn very detailed since I drew "the eye" and needed a challenge. So I made the entire drawing with a mechanical pencil (A4). It took me quite a while, approximately 35-50 hours.
