It's a neat picture, even if sparsely populated with objects. I don't
understand what those two tiny objects are at all. But it looks like a oil
painting to me, pretty neat. Hope any media success doesn't change that
aspect too much. Your trouble sounds just like the things about
'atmosphere' from version 3.0*. Either too thin or too thick. You could
try lowering density floats or vectors as you raise the scattering
(emission and/or absorption also) float or vector and vice versa.
Basically you have to give the light enough to interact with while not
inundating the media too much.
As Stephen pointed out it will always depend on the scene, like area
confines and lighting.
