In & Out of clothes! I just love that huge contrast between the full classy smoking dress & the all naked, vulnerable side, hehe!
Some could say that sounds promising. ^^
On the left side I used my lighter graphite pencil, which is used for quick sketches, sometimes building and also for shading on the final pieces. The naked one on the right is closer to a final version, although I drawn him kinda quickly, sketchy style.
