I have tried to lighten the figure without the end result looking 'false'. I think this has worked very well.

The exercise is again asking me to consider the limits of this image manipulation. I find the level of work carried out here quite acceptable. Even if I had lightened the figure more, I don't feel it is telling an 'un-truth' although the image will look false. My reasoning for this is that the image is still displayed as it was seen albeit a little lighter.
This is of course all highly subjective. Other photographers my have different opinions. My own opinions differ depending on the final use of the image.
