What you've got there isnt bad, if you were to remove the reflection on it.
They should be dull.

also reflection is fine what if it was a metalic based ring? no polution from
dirt on the metal and it would be slightly glossed, just use mega pov blurred
reflection

What are the circle and line symbols over the planet
for?

This isn't bad at all. The rings on "our" planets vary greatly, so I can't see
why these shouldn't be just as possible. Well, I'm not sure if you that strong
highlight is realistic. And ambient should be 0 for planets.
I've made a fairly detailed Saturn ring texture, but I don't think you can use
it for anything else. It's in the binaries.scene-files group if you're
interested, posted 28.11.99. It's also available from
http://www.stud.ntnu.no/~as/down.

Here's an image of what I would do. You will need the SuperPatch or MegaPov to
use it, though.
Here's the code for the ring:
disc{
<0,0,0>,<0,1,0>,10,6
pigment{
function noise3d( sqrt( x^2+z^2 ), 0, sqrt( x^2+z^2 ) )
scale .4
color_map{[0 rgbf 1][1 rgb<1 1 .9>]}
}
finish{
ambient 0
diffuse 1.5
}
}

Each individual particle might reflect, but those reflections would be
in totally random directions because the particles are oriented
randomly. Take a look at a pile of iron filings.

Isn't this precisely how blurred reflection in MegaPOV works?

Actually, it is 0. But on the other hand earth shines quite a lot. It doesreflect
~39% of the light it receives. A ring in low orbit would have a
good 'earth shine'. If the moon does, after all...
