I’m happy with this now. The most important change I made was to Lavina’s profile shape. The bone above her left eye was too prominent and the shape was too angular. Her left ear and left horn bud also needed tweaking.
I refined the modeling on her body and worked more on Adam’s knee, finished the halters, worked a little higher on the grass, and enlarged the shadows.
I also brightened Adam by adding orange highlights and glazing over some of the highlight areas, particularly on the face, with light blue. I also worked quite a bit more on Lavina’s eye to, hopefully, enliven her expression. So now it’s time to leave them to their nap!
