Hastily-made interior

Thought I'd try my hand at a quick interior. The frame below was rendered with Mental Ray, Global Illumination turned on, using an Area light (scaled to the size of the window) with an intensity of 0, and a photon emission of 1900. The scene is roughly the size of Maya's default grid space. A directional light with an intensity of 1 is present to illuminate the photons emitted by the Area light.
