More Head Doodles

For the two heads on the bottom, I was looking at an old photograph. I didn't try to do portraits but they came out pretty close to the pictures anyway. I avoided their hats, not out of fear (for they were very fancy hats) but because I had to leave for work.
...Then I did the top two, no reference. Freestyle. The bottom faces look more "real," I suppose, but that's only because they were.
