Okay, I've worked on the shape of the face, tilted that eye on our right down slightly, raised the lefthand corner of the mouth and smoothed the lips, both upper and lower, evened out the skin tones and made them slightly tanner, and played with the eyebrows. I just sent the url to the clients and we'll see what they say. I think it's a good likeness now and I only hope that if I'm right, they can see it. Sometimes after being dissatisfied with a likeness people have trouble recognizing when it's finally achieved.
Here's the closeup of Danielle and the url for the new version of the whole portrait, although it's slightly cropped on the right.
