The father paints a portrait of a girl who is staying at his house and then finds out that she is his daughter

I guess, it was european film (italy, spain or france). Or it was just location. The man lives in his house somewhere in mountains. And there is a young girl (with company, it seems). He doesn’t know she is his daughter and starts to draw her portrait. Then, his ex-wife visits him and tells him, she is his daughter. Then, he finishes portrait.

It seems, portrait was with partially naked breast.
