I've added a 2nd light (no shadows) to shine on the case of the clock. Key light is right where I want it as well. It looks close to how I want it now.

The thing I am not really sure of is whether I should add more shine to the materials (gold and copper) or not. They don't look quite metallic enough, but I do not want more reflection either. What could I do to make them look closer to copper and gold?
