Help to light a interior scene

I made an interior scene, But I need advises to light it up. The camera focuses in a corner and right now the only source of light is sunlight coming through a window. But that’s not enough Lighting.

Hi, you could add a big mesh emitter backside the camera with low emission, or put it at the celling.
Try the Window Lights method from wiki:

Cheers, mib.

EDIT: small test file:

Hi, maybe a weak backlight behind any kind of things like chairs or desks…
