I might have mistaken your earlier comment about the ivory-effect as to describe RICH image. This shot clearly demostrates what you have described, and I really like it.
Yet I still have to be picky :), just a minor one this time: I don't like the frame you put around the face.. a bit too heavy to my taste. More importantly, since you are in a Chinese forum, our tradition of using thick-black frame around a full-face portrait is exclusively for the deceased.
