Perhaps a little empty, but if you would put some other rocks it could od it !

Skyrim rocks is also a trick, they use good LOD also, and like Oblivion, in a town you'll see that everything around you are detailled, but the level is empty some meters after (even by adjusting some good distance).
They have a good fading LOD, the ojbjects appera with a smooth alpha transition as you come near (to be less heavy in terms of polygons to render ) : and you even notice nothing if you are playing and don't concentrate to remake it
You could make a lot more general big rocks, than with LOD or
Alpha fading object add more rocks or details ?

Or perhaps you can adopt Borderlands style, with interconnected levels ?

Anyway, i find this level looks great in terms of colours, ambient lightening and atmosphere
