The picture only shows flat color while rendering. Open the Lighting window to see the effect of lighting (in the lighting preview until you apply it to the full picture). There are lighting presets of various kinds. (In the 1.6 Basic category there is one named 'Front diffuse' that matches the main window preview). In general, lighting looks best with some shadows, and the shadow angles need to be set before rendering. You can preview lighting while rendering, but the render needs to be stopped before you can apply lighting. The big button at the bottom of the lighting window can do both.
