Diana Rigg?

I do love drawing people, but there is less chance now of finding a subject. So when BBC 4 just showed a half hour interview with Diana Rigg in a programme called Face to Face from 1997? The image of her was full face far away, full face close to and profile images, so her face was fully in view was for approximately ten minutes. It’s a good bit of practice, as if you were drawing from life. The face never stops moving so you have to try and fix where the eyes are, how far apart, how long the nose? And the shape and size of the mouth. Plus the face shape. How long is her chin? How high her cheeks. Trying to see all of the face, not looking too closely at just one bit, so it fits?
