Aye, the lava planet looks good, but the lava must be really bright to be clearly visible under daylight area.
Might be wort experimenting what it would look like if you made just a shallow crescent of the planet lit by direct sunlight, and make the lava emission spread onto the atmosphere and dimly lit the shadow side with both the atmo and the lava glow.
I've been struggling with HD mishaps... long story short, had everything backed up and wanted to re-install Windows for reasons unimportant here, but the recovery tool decided that it liked the backup drive more and formatted it, and installed Windows on that HD... didn't lose anything *really* important, just almost all my downloads which were on the other HD along with the backups of the primary partition of the OS HD...
Also, practically everything put here lately looks rather fine.
I've been experimenting with methods of making a texture with craters so that they appear round all the way to the poles. Found a way, too, but haven't had the chance to actually use it to make crater-filled planet surfaces... it involves making differently sized round brushmarks on the texture at more or less random intervals, then using an edge filter of choice to make out the round edge mountains of the craters, then apply polar distortion filter to spherize the texture... it results in practically zero (or damn close to it) polar distortion when the image is wrapped on a sphere later, but it means you'll likely need to clean up the equator a bit to make the two halves fit together - that can be pretty nasty sometimes.
