EDIT: I thought I'd put the finished portrait here and compare it to the 2 hour session. I tweaked a few things, adjusted a few colour and now I'm calling it done. On to the next one!I wanted to continue with the Zorn palette to work on a portrait and tonight there was a perfect chance as one of the images for the All Media Event on WetCanvas was a portrait.
This is my attempt after two hours. I still haven't got the angle of the head quite right, but its coming along. I quite like this limited palette for portraits and they especially suit the ruddy complexion of this individual.
I'll do some more work on it tomorrow and see if I can finish it off.
