Supposedly a gas giant with it's moons.

This uses the new moons macro.

I like the texture on the moon but the planet looks a bit strange; don't
gas giants typically have swirly horizontal bands and more elliptical
spots?  Though I'm not quite sure how to do that procedurally, maybe
with black hole warps.  If it's just to look nice though it certainly
still looks nice.  :)

Oh, and possessive its has no apostrophe.  >;)

The cloud patterns on the gas giant are rather weird. All the gas giants
in our solar system either have cloud bands or are very plain.

Similarly, the texture of the ring looks weird. The texture of Saturn's
rings runs around the ring (like grooves on a record).

There are far too many moons in similar orbits. Their gravity would
interfere with each other each time they passed, making the situation
very unstable.

The dark side of moons and planet wouldn't be illuminated. There's not
much ambient lighting in space.

The Sun seems to be extremely close. The nearby moon and the planet are
illuminated from such a different angle that the light source must be
not far off the edge of the edge of the ring.

It must be a very massive "superjovian" which has, due to gravity
compression,
its own internal heat source, producing surface patterns by convection
which
look similar to the granulation on the Sun's surface! Also, such a massive
gas giant
should glow faintly from its own inner heat, and this glow would be visible
on the night
side - what about some reddish ambient light?

Yes, and there are far too many large moons too close to each other as well
as to the planet,
and the ring is way too simply structured! As an example for a more
realistic planetary ring,
I attached one of my preliminary spaceship renderings...

You might want to use some NASA pics for reference if you're trying to 
create a realistic scene.  What you've got now looks toonish because of the 
number of moons, the density of the starfield, and the high level of 
ambient light.

Here's a few examples of what planets look like in real photos:

Interesting. :)

Thanks for all the responses.

As to the oddness of the gas giant - I want this one to look really alien, so I
abandoned the bands and vortices look.  I wouldn't mind a way to make the surface look
"hazier" though.

It's amazing what a little lens flare from Photoimpact can do.
