In the last session, I refined the ear and began the hair. The blonde hair will be applied over the dark underpainting but some of the darker areas will show through the lighter tones. The natural colour is  slightly darker at the roots but very blonde on top which has been accentuated by sun bleaching. It seems unusual to have such blonde hair and brown eyes but obviously with natural selection of genes almost anything is possible.
some of the darker streaks on the forehead are shadows as, not all hair lies flat on the skull and it needs shadow to indicate dimension.
A long way to go yet but I am happy with progress so far.
In between working on the portrait I have been preparing a watercolour painting bases on ladies scarves as displayed in a store. It will be a sequel to 'Le Scarpe Delle Donne'
