Kevin, I do love the face and believe the shirt addition really keeps your eye from getting confused. I wasn't sure where to stop before, kind of ghostly...meaning the figure was evaporating up to me.
I am sure this is not where I should ask this of you, but I would love to hear more about your transition from commercial (graphic) arts - portrait arts. I did the same thing last year and have loved every minute of it. I am new and did not notice if there is a general chat thread area. I'll take a better look.
Isn't all the above input fantastic? Who'd have thought Chris Saper and the rest of these wonderful teachers could give you input. In awe here!
