Wow, David - I continue to be amazed by this portrait. I've seen it in person and it just takes my breath away. One of the things that impresses me the most is the control you have over the wide variety of colors on your palette. Furthermore, your drawing skills are enough to make everybody else go home and beat our heads against the wall.
Actually, you are starting to be a little hazardous to my health with all this breathless headbashing.
Congratulations on this powerful painting, David!
