My dear friend and roommate, Shayna, drew the outline of this one and I filled it in. I think it took Shayna about 5 minutes to do her part (because she's quick and knows what she's doing) and it took me about 3-4 hours to do mine. Shayna totally rules.
Drew this on the back of my time card at work over the course of 3-4 weeks, 30 seconds at a time here and there starting with the "FAXED" stamp. Just kind of a sketch/scrap drawing. I haven't worked on any "serious" drawings for a while.
Also, I got really attached to this little thing I drew on a notepad at work.
