Awesome, the red in the space looks great and the green light. I'd tone down the soft brushes. Everything is blurry, so there's no focus. Smudging is fine for the base layer to get local color and form lighting, but then you gotta add the direct lighting and the hard deets. Save the blur for deliberate depth of field to push stuff back in the composition. You'd think the surface of earth would be smudged from this distance, but if you find a good photo, shit be sharp and high contrast.
