Nothing is lost, just forgotten. We have a light coming from the top, directly onto the face, you see only outlines and shadows. This is from the library, reused and repurposed.
What you see is not what was intended, it was found coincidently and modified to fit its new purpose. The need to revisit older work, or even something recent, form a new prospective, see it and forget it — it might come back as something different.
