Looks quite nice I think, you're getting great variation in the cloud heights/shapes, and some beautiful lighting. I think at this height the dark/shadowed areas would probably be darker, there's nothing bouncing the light down there but atmosphere, but maybe that's enough. Personally I prefer with a simpler lens flare, the "dashed line" outer part is a bit funky IMO. The X-37B model is a cool idea, but somehow doesn't shade realistically IMO? Might have to do with the tonemapping or overall contrast of the image though. White would usually be whiter, black blacker (higher contrast). But perhaps it's a texture issue? I don't know. Also, I do see the black line at bottom, but *also* on the left side, but only in the version with the X-37B model. They're both 50-100 pixels from the left/bottom of the image.
Anyway, very promising stuff. Too bad about the render time, but I wonder if you're raytracing the atmosphere. I ask because even though it can sometimes result in higher render times, it *does* capture fine detail better than higher detail can except at really extreme levels (>1). So you might try a crop but reduce Detail to 0.5 or even less, and put cloud quality at 2. Be sure to adjust Atmosphere Samples as well, and try not to use AA above 4 (should not be necessary in the version without a model).
