Detail.
When putting in the latest figure, I noticed that the waving man was out of scale. He is too large to be slightly behind, or level with, the figure just painted, so I shall remove him and re-draw.
The figure I worked on today will need some minor adjustments which I shall do in the next session. I feel the need to add more to the right-hand section of the composition and, so will also begin to block in on that section.
