A few more comments about the picture that I am working on (see Two Commuters, below) of an old couple on the train. They were a lively pair, having a completely ordinary conversation - about the Rugby World Cup, as I recall! They seemed younger than their years.
I am painting them in the style of Gerhard Richter, but this surprises me, because when I think, it doesn't really reflect how I saw them.
They should be in warmer colours. In comparison with commuters, they were a lively blur, as warm as the blur outside the window of the train. All the same, I am happy with the way things turned out. As an experiment with the technique of blurring, I think it has proved reasonably successful.
