Hi Chuck,
You did a splendid job with the underpainting, with all your hard work!
I realize that the painting is in progress, and have a few suggestions (I assume you want some feedback, since you post this under the 'Oil Critique' section):
The skintone (as well as the upper half of the painting) look very 'warm' right now.
The colour and value of the background is too close to the colour of the subject face. I would change the (colour or value) background to bring the face to the viewers' attention a bit more. Are you in the process of glazing another colour over the colour of the background?
It also seems like the upper half (background) colour is competing with the colour of his shirt. I would determine a local colour and that would be the 'dominating' colour. Right now, the blue of his shirt and the background colour are competing with each other (not sure if I make myself clear here).
Are you glazing this painting, or painting directly over the underpainting?
The more I look at this painting, the more I like the subject's expression. I look forward to see the progress of this painting.
Sincerely,
Mai
