I was chatting with a friend some months ago, during which, with permission, I attempted to draw her. Last weekend, I tried this again in paint from a photo taken at the time. I had in mind my visit to the German Impressionist exhibition last week, but there is not much of that style here. Also, unfortunately, while her face has all the right bits in place, taken together they do not turn into a likeness.

The final painting is very expressive.
I think in the end you have to look at the painting as a painting and not worry about the likeness. You have succeeded!
You keep refering to the German Impressionists. I think you’ll find they are Expressionists, for reasons I pointed out before.
You’re likely right. I’ll double check
