Thanks for looking! I'll post for sale soon.
The subject (left), and my initial layers of paint at right.
Up through this image, I've only used three colors - burnt sienna, payne's gray and white.
I may revisit the tape when I'm a little more awake. Note that the shadow here is a good bit softer than the subject; that's because the light I paint under creates very harsh shadows, and I've found them to be unconvincing when replicated in paint. So I always knock my shadows back and "eyeball it" until it looks convincing to me sitting in front of the piece.
***As promised, I revisited the tape and the shadow a bit, as shown below.
