The painting continues. First a couple of sessions with more spontaneity than precision, often a good way to start I find. Then raising the strength of the colors to bring out the effect of the sunlight and shade.
A bit more time, but not too much, on the two figures and it will be about finished.

A detail, if you click to see larger it should be close to life size, to appreciate the brush strokes
