I decided (for better or worse) to sacrifice the statue further. Inspired by a reference image,
the plan was to add the blue patch+streak to Harley’s left eye, lip-stick smudge, face-dirt,
whiten her hair as the main section looked too yellow.
The blue patch+streak turned out wonderful. I mixed and applied the blue patch to the area
below Harley’s left eye. I then used a single strand of paint-brush hair covered in thinner to
cause some of the blue to run / steak down Harley’s face. The experiment worked out.
