Good grief, Marietha - this is absolutely amazing... well done!!!! However did you achieve it? It's so 3-D I can almost feel the indentations and reliefs in the image's surface. Not sure why you've called it copper... looks more like brass to me... copper has a more pinky-rose hue. Excellent bit of digital enhancement!!
Composite Caedes?
Compound Caedes?
Metal [or Metallic] Caedes?
