Cindy, Michelle, thank you for your comments.
Yes, I delivered it already. It's too late to correct. But he liked his wrinkles anyway

. Actually, Roger Cairns was my former painting instructor, and he suggested that I paint in a large size and focus on the face for a more impactful and contemporary feeling. He wants me to try even double the size of these paintings in the future.
I think Jen explains well about the large square size of these in my "Mrs. Holly Cairns" posting section. I agree with her opinion.
Michelle, I think it's too warm too. I used little bit of ultramarine blue for shadow side, but it was not cool enough. I'll not be afraid of depictions of cool shadows for my future paintings.
And I tried to edit this photo color as Cynthia gave me the tip for "Holly Cairns". Is this better?
