My entire point of this was to have the shadowy figure in the bottom corner of the image. I'm thinking, that the answer to this is less "kill all the empty space" but instead something more along the lines of fill the space in... an empty fashion.

The focus is on the shadowy figure, it's easy enough to draw attention to it with the contrast of its eyes on the blacks and greys. Putting him in the corner gives him more visual weight than centering him, and since there is a lack of visual interest elsewhere, and a line given by the slanted road/surface/thing the eye is more or less forced to focus on him. I guess it's just boiled down too far, having nothing be in the black fog. It is varied, by the way, but I may need to reduce the brightness on my home monitor, at work it looks a lot more uniform than what I was looking at last night. What it needs is... a setting of some sort. Nothing too visually exciting, I want attention on that corner. Hm...
