Hi Don I had a cursory glance through this and was immediately worried about the upfront section on light wrap (don't worry read on).
I battle a lot with mid level and sometimes senior artists with light wrap. Often I'm presented with s shitty comp with light wrap thrown on top to disguise it. So I make them take it all off and improve the key. However I was pleased that you go into the need for this to be subtle and in your example it is subtle. The only thing is, I teach this as blending the fg and bg colours due to the fg being sampled against green rather than a true bg colour. When you remove the green you don't get the bg pixels' blend you get the same pixels without green. Hence the need to blend the bg colours and mimic a camera sample against the bg. Lightwrap to me is taking the brightest parts of the image, assessing whether or not they would bleed into the FG (like a light source would) and then blend this in someway. It may be semantics but I find talking about how pixels are sampled in a camera and hoe they create an average* colour at that point (*over simplification I know) and why you need to 'resample' against the BG useful. Then lightwrap becomes a technique of it's own. So in your example the feet would need a blend too, and light wrap would be applied on top. As I say it was a cursory read so may have missed you make this point earlier. Nice work though.
