Celeb Portraits

I continue to have an interest in portraits and received some very useful advice recently.  Here's the gist:  most photos of our friends are taken with cell phones and do not have adequate lighting to create a good portrait, leading usually to unsatisfying results.  Lachri, an artist I support through Patreon, suggests that we work with celebrity photos as these are always professionally done.  So recently I have nearly completed two:  Tea Leoni and Catriona Balfe.  I think they show significant improvement over my earlier attempts.  Then when you feel confident with skin tones and textures you can switch to the lesser photographs with a better idea of how to improve them.
