I've been working on this one this evening. The light needs to be tweaked some more. I was going for strong hard lighting though.
Detail 0.5 Global Illumination 2, GI detail 1, GI samples 2, super sample prepass.

An unexpected error occurred during the render. I posted the terrain with the error in the support section. Please feel free to use it; I'd like to see it full rendered, or if someone else has the same problem.
