The shadow below the bottom lip will continue up to the ear, as the light is cast from the left of the composition and the collar of the jacket is lifted partly over the face. There will be some shadow on the right also, but not so far up. It is these shadows which will give the 'intimate' feeling of the pose.
The lips of young children are tender and the colour delicate, which is what I am aiming to portray. I am not finished yet, and will work on them periodically as the painting progresses.
