Sketch of a poison dart frog

A sketch I did a few days ago when i still had energy.  The new studio job is really tiring and intense...I think.  Not sure if it's because I haven't been tied to regular hours for a very long time and there really isn't a lot of break time at this studio or if it's because I've been working almost non-stop for a very long time.  Not sure.  Am exhausted though.  I will need a bit of time off during Christmas...because January is officially booked almost immediately after New Years.  Looking forward to my vacation time in Japan.
