The most notable thing was that the areas of Burnt Sienna and flesh tone were too contrasted, so I toned the darker areas down with a thin glaze of flesh tone thinned with white spirit. This effectively muted the darker tones which now showed through the glaze as under painting, giving a slightly more pleasing effect across the legs and torso.
The painting has given the figure a slightly 'hairy' looking texture, so later today I might clean back some of that with a little white spirit.
And the lesson to be learnt from this, Mr Day? Don't try painting in half light.
