I did this drawing over a few weeks. Not that it actually took all that long, it's just that I tend to work on various things at sketchnight. Sometimes I work on commissions, when they're not smutty, sometimes I'll try doing a little painting on the tablet PC. Still need to get a programmable keypad for those ever-so-useful hotkeys.
Also, I like the way the drawing was turning out, so instead of leaving it in some 3/4 finished state, I actually finished it. Maybe I'll try coloring it next time.
