The Long And Winding Path.
Photoshop, Wacom Intuos, 2010
Original size 5400 x 7000 pixels.
This started out as a quick sketch, but the path got longer and longer and more and more twisted...
So 20 hours later I can conclude this was not exactly a speedpainting!
I guess you can spot the features of a face in there, if you really want to.
