Sometimes you don't notice discrepancies until you see things in a different context. This is one of those cases where I had scanned this painting at an odd color setting which boosted the saturation and contrast of the shapes. It looked much better than what you see here, so I'll likely take this home and rework it to give it more punch. I'll also clean up the line where the white is lost.
Now with more contrast in the shadows and the wires which I'd forgotten to add.
