Ok here's an updated version: it now has an atmosphere, the mountains have a 
normal map, the ocean has a fairly realistic material, I've tweaked the 
relative scales a bit (though this planet is still far from realistically 
scaled), and the cities have a small amount of ambient to glow on the dark 
side of the planet.

But by far the best thing is the atmosphere, it looks way better now IMO. 
Though inevitably it also takes many times longer to render (it's still 
quick).

Oh, and I know: it needs clouds! I'll do them next.

Any other suggestions/questions?

Well done indeed. Only thing which - as a professional - strikes me as 
really odd, are the mountains. They look too much like random patches 
dropped here and there. Mountains come in extensive ranges, winding over the 
continents as a result of (ancient) plate collisions. That would be a nice 
addition to your work.

Are you saying that it needs a bit of intelligent design? :)

These images reminded me that I had my own POV-Ray planet-generator 
somewhere on one of my disks :)

  Assuming this planet is about the same size as Earth, the visible
atmosphere would be about 240 km (150 miles) thick. I wonder how
realistic that is... :P

Well done!
Suggestion? A night texture, with lights over the cities.

  What if it's a planet without civilization?

I based it on photos of earth :P

Though the scale of this planet is really inconsistent, the cities & roads 
are way to big (seriously, roads visible from space!). It's only intended 
for use in the background of one image, and it's meant to be a futuristic 
earth-like planet, so I'm taking a lot of liberties for artistic license. 
The main aim is to make it look "planety"...

So criticisms & suggestions are appreciated, but I might choose ignore them 
;)

Those glowing regions just on the edge of the dark side of the planet are 
meant to be cities at night (the patches of grey dotty areas are their 
daytime versions), though at present I've just added a bit of ambient glow 
to the city pattern (Rather than a more realistic pattern of lights).

LOL!  Yes, from a "major" deity... ;-)
