I liked the way this one turned out.
Having just made a first attempt at a planet, this got my interest. Obviously, this image just didn't happen without a fair amount of effort being put in to get the sci-fi effect. It worked, in my estimation. The squiggles reminded me of Windows 7 start-up screen.
rat.
Extreme! ;D
My only issue is that the starfield covers the left "shadowed" side of the planet. One could argue that the sun on the right is not illuminating the planet correctly but I guess this is a twin star system and the main light source is behind the camera to the right.
Good work
