A tough room. You're right, the eyes do bug out a bit too much, and while I noticed that, I think they are more right than wrong. Actually, the hardest part, now that I mull it over, is the area around the eyes -- the brows above, the bags and wrinkles under and on the side sweeping into the temple -- all that complexity. This drawing does that part well. I always find his nose, his lips, his hair, the beard, quite easy. I only spend a few seconds on those when I draw him. But the eyes and how they are set into the head -- that part takes me a while, with corrections and going over lines.
