Thanks a lot for the comment.
I noticed already a long time ago your Admiral, and am also amazed by the delicate treatment of the hand in your picture of Mr. Schnyder.
Unfortunately the close ups are not precise enough to see more the "secrets" of such a final "foggy" effects.
I think my technical problems would be resolved if you would be able to tell me how many levels you use in your faces: is it a kind of "a la prima" but in a very smooth way or are you using several levels of colors (like on the front of the Admiral's head, the right reflected light) after the first levels are dry?
Maybe you are giving lessons in Greensboro? Or in a virtual way through a web cam?
Best regards,
