The bottom left hand corner is almost complete. I have blocked in the back of the chair with some highlights and adjusted the profile of the figure a little. All these additions and changes are subtle but are important to achieve the effect that I am trying to achieve. The differences between yesterday's entry and todays may be small but, I feel, are important for me to include before I continue.  If all goes to plan tomorrow, I shall work on including the bending figure with the hair bun and blocking some of the background.
