I try to vary the conditions

- I look at myself with or without glasses, I put on a hat or not; I draw from a photo if I'm in a hurry (yes, yes, too much to do!) ...

- I change medium: pencil, oil paint, gouache, markers, oil pastels, collages ...

It's a good exercise, an asceticism, a test too! It is not often similar and I do not realize it until after. I don't look at myself often and don't see myself as others see me ... and that's better.
