Well I kept meaning to post an update today but could not stop myself from painting long enough to take a photo. The old, oh just one more tweak game ;)
I have been working all over the painting now, on the mother in areas and on the son further refining the features and darkening the darks where needed. The mother's features are getting closer, just tweaking needed now in little stages and softening of areas. Her lips are closer but still need a bit of shaping and her bottom lip needs softening which will make it appear a bit fuller.
I have added the darks to the child and I do not think anything on his face will get darker but areas will be shaped and softened in stages.
