Coffee Drawing...working during breaks

I did the sketch of this for a job a few days ago.  The roughs have already been approved and I'll be doing the finals shortly.  This month is insane.  I may spend my birthday working at this rate.  I know, I might have taken on more than I can chew but I love illustrating and animating...the only downside is that I can;t work on my own personal projects.  Something I've had ti give up the last few weeks.
