Second attempt, different lighting arrangement.

I've added a circular platform and animated it moving at roughly the same pace as the character and 2 pointlights. The first pointlight is below the floor near the bottom, with the decay rate set to Quadratic and an intensity value of 4.45. The colour is a yellow which gives off a golden light that i'm not sure will work well with the rest of the composition, so that might need altering.
The second pointlight is at the top of the shaft, has the same settings as the other except no decay.

Think i'll definitely have to have at least 2 lights, might animate the first pointlight to travel up with the platform so it creates a glare/shadow on the backwall.
