If you just intended at cartoony caricature of a ringed gas giant, it might be o.k....

...but if you go for the real thing, it just hurts to look at it!

Firstly: Jupiter has more and narrower cloud bands than your planet, and its colors,
ranging from almost white to butterscotch and brown, are generally more subdued (at
least on images taken in visible light). Then the cloud bands are not as large-scale
turbulated as in your picture, but contain several oval eddies in different colors,
the most famous and long-lived among them is known as "Great Red Spot" - perhaps you
could try warp functions to emulate this.

Then the ring particles are waaaaaaaaaaay to large - each single ring "particle" in
your image would qualify as a true moon of Jupiter, and several of them are even
larger than Earth! In fact, Jupiter's ring particles are only the size of cigarette
smoke particles - and also very dark. At this scale, Jupiter's rings are almost
unrenderable, and probably even an astronaut passing by wouldn't see anything with his
naked eye.

As you mentioned, the sun needs improvement too. This could be achieved most easily by
replacing the solid sphere by a media sphere with a spherical pattern, the color value
at the center should be 2 or even 3, to make the sphere really bright.

And... in the real Solar System, there are of course no other light sources even
remotely comparable to the sun, so you won't ever see a lit hemisphere of a planet AND
the sun in the background, unless the planet has a large bright moon (like Earth), the
hemisphere facing away from the sun should be in complete darkness!

See you in Khyberspace!
