Having Tea with Me

I did some sketches of three celebrity faces. Zhang Ziyi, David Gilmour, and Benedict Cumberbatch. I only used my fine-point pen and I also chose to use the other side of a used piece of paper; so you may see designs on their faces from the other side. I felt pretty proud of what I did; not so much the decision to put the smallest head on the bottom instead of the top. Tell what you think. Good likenesses?
