I managed to get a hour of painting done Sunday evening, attempting to get his beard detailed.
Originally it was painted off white but after subsequent highlighting and washes, everything looked too bland and uniform.
I ended up going back to the drawing board and settled on trying to paint the beard in various grey tones followed by some darker washes.
Now he appears to look more like a Gnome than Santa!
Base colours were added to his clothing, just about time to start on highlights and shadows..now I just have to hope that he doesn't run away in the middle of the night ;-)
