After you have set up your cameras, just as in a real photo studio you can set up the appropriate highlights. Use the HDRI editor and you can draw highlights directly onto your model where you want them to appear, then HDRI editor adds the lights appropriately in the environment map. Make sure to texture every part with large, high quality textures because the eye can spot undertextured areas. For added realism add some luminescent panels with colored light (warm or cold) to subtly illuminate the sides of your model.
