I added another figure today but he is different from the others.  The other figures are all focussed on the cooking but he engages with the viewer with a wave. I find , like a lot of artists, drawing hands to be quite difficult especially an open hand facing the viewer. The most common error is making hands too small. If you place a flat hand on the front of your face you will discover that most hands are as big as the face. Whilst this is quite a large painting, the figures are quite small, so any slight change in angle makes a big difference to the accuracy of the pose and proportion. I have shown the full canvas to give an idea of the size of the painting and a detail which shows the drawing a little clearer.
