Not too exciting yet. Time to add in some light. For this scene, we use three radial or omnidirectional lights, and one spotlight. The radial lights give the general lighting to the scene, while the spotlight is used to highlight the dial. It's useful to use top views to see how your light falls, and make adjustments to their position or settings as you go.
Saving often is a real necessity here.
Now we have a scene that looks like this. Nice, but something's missing. Adding some props would really liven up the image. Thinking like a photographer or painter is really the key to getting a good final product here. For some strange reason, the Minerva just conjured up a wine and roses imagery.
