Render???

I was watching the Bruno Mars video, and at just over a minute it shows him over a background it looks really cool- what do you reckon for our film?

I tried using a Ramp Shader to make the outline and then have the rest of the scene black then used After Effects and the Luma Key to remove it. I think it could look quite cool and you can use a few colours to add shadows or highlights.

It would look like a scroll story... what do you reckon?
