Never mind, I've got this.
But now I'll have to figure out how to soften these shadows. O_o

The light is an Area Light. Could this be the problem? Because so far no settings can soften these shadows.

I think I could use Maya Software for reflections that don't need to be too accurate with textures (since it blurs in render) and use Mental Ray for more precise reflections.
So far, Spotlight seems to be the best light for shadows.
