I thought about a keyhole shaped vignette for this, but I think this works really well if not better.

 

This yellow series turned out so great! I was blown away as soon as I saw the shots in the camera. So awesome!

 

Lighting was a Nikon SB-600 in a collapsed umbrella high and barely left (so it and I could both fit in this hallway), a bare Nikon SB-600 pointed at Tiffany from within an office just off the hall, and an SB-28DX around the corner with a yellow cover on it made from a school folder to turn the white wall yellow.
