Steven,
Thanks again for your insightful comments. I did work on the portrait yesterday. I examined the eyes closely and think that maybe the eyebrow was too high. The eyes seemed to line up enough to satisfy my not "messing" with them. I did lower the eyebrow (which did seem slightly higher and out of line from the other). The change is subtle but helps.
I worked on his right side in shadow and the edges. Might have to go back to that again. He is a rather chubby boy so he does have a lot of cheek to work with but I want it to be flattering yet capture his look. The mom loves his dimples and wanted that incorporated even though he isn't showing much of a smile.

The client is another story for another topic, I think.
I did just what you suggested with the chin and it works. Thanks for the "nose tip".
Would love to see some of your work. Are your paintings anywhere out there in cyberspace?
Thanks again!!!
