The most striking thing, I think, about the portrait is the elegant length of blindingly red robe which captures the eye and doesn't let go. In my personal opinion, red is a very difficult color to paint well, whether it's fabric or flowers or fire engines - this is a masterful handling of the color. And my goodness, the length of the doctor's body, very impressive. I wonder how tall he actually was in life. Again I think, Sargent's penchant for elongating the human body is on display here. Personally, I love this about his style - it adds an odd note of otherworldly 'impossibility' to the strength and beauty of the portrait.
