Had something like this in mind for a while now…
The plan is simple - midnight setup, some dropships flying through a canyon of sorts…
Anyways, worked on this for a few hours (sculpting turned out to be surprisingly easy way to do terrain) and, well… check below the render 
It already has some nodework (the glow effect, the moon looks bad w/o it but it still needs some loving), otherwise the base terrain is mostly finished (got a little bit more to do but it’s in the dark (there be monsters ^^ ), the water might get some tweaking (also gotta add a waterfall, explore the right side of the canyon and you’ll notice the spot) but otherwise it’s going to stay as it is. Well that is if I don’t get brave again and try to do something like the dropship flying really close to the water at high speed but I don’t think I’ll be able to do that (on the other hand that might be a perfect oppotunity to learn the fluid simulator) 
The lighting - it’s damn simple at the moment… I’ve got a possible concept in mind involving some lights in the canyon and a blast door/structures on the left side of it to indicate that there’s a base there (sort of like ironforge from world of warcraft if you know what I mean, just made the comparison btw)… Or maybe just add the battlecruiser to the fray and make him use spotlights (don’t worry, that’s a last resort ^^). Otherwise the canyon is a little bit too dark for my taste… (AO is unusually high, I’m aware of this )

Probably going to feature 2-3 of these…
