I have added some colour to the mouth which helps to convey the expression.
Darker flesh tones have been added over the pale underpainting which can be seen more in the lower photograph.
I am now beginning to enjoy this painting. I am always a little apprehensive when I start a new work which is probably why I am such a slow painter!
There are many tones and details to be added in the hair and face yet, but I may under-paint the coat/jacket in my next session which is the large area just below the mouth. This coat casts a shadow on the lower part of the face which will be an important part of the composition and will add dimension.
