I have added two photos to show my development around the lips. The one from my last post has the top lip only blocked in and, whilst in the photograph the highlight looks quite natural, in reality it is a scant bit of exposed canvas.
I added more colour and tone around the mouth and to the top lip, and  the start of the shadow to the right of the composition.
I am trying to achieve the colour and delicacy of the skin, which is usual on the lips of very young children.
The reflections were then added caused by the moisture from the lips being licked by the subject.
There will be a few more strokes of different tones added when the present stage is dry and, tomorrow, it is my intention to apply some colour to the ear on the left of the composition.
