So here's the scene I've been developing that planet for.

It shows the re-birth of a solar system from the remnants of an earlier 
star. The image is rendered with a 380 degree horizontal field of view, so 
the star that goes nova at the start is the same one at the end :)

I need to do some work tying together the different parts of the scene, and 
that lava rock in the middle looks wrong. Plus I want to add some spaceships 
evacuating the planet at the end, but I might have to skip that bit to get 
it finished in time.

I assume you're going for constructive criticism so I'll save the praise.  That
said, it's already very impressive.  You're really a master of POV-Ray
textures.  Nevertheless:

- The protoplanetary disk fades out and gets very smooth at the outer edge.  It
might be a little more interesting if it were wispier, but I'm not sure about
the physical accuracy of that.  Maybe it just needs a little more contrast in
the colors.  I guess jets aren't out of the question either.  You can google it
as well as I can, but:

http://www.indiana.edu/~rcapub/images/MMWaveDisk.jpg
http://hubblesite.org/newscenter/archive/releases/1995/24/image/a

- Second, I'm not completely sold on the layout.  There may be a smooth curve
from one end to the other, but it feels just a little loose since there aren't
quite enough objects to tell for sure.  Maybe if it were a little stronger or
if the image were a little taller and followed a layout more like:

*__
    *_
      *
     *_
       *__
           *

Again, I know that's very invasive; I'm just saying what comes to mind.  I just
have a hard time getting completely absorbed in it with a 5:1 aspect ratio.
For example, this one guides my eyes a little more:

I know time is winding down though, and it's a wonderful image no matter what.
Good work

Thanks for the comments, I mostly agree with you but there's a lot of things 
I still want to add to the image so I don't know how much of this I'll have 
time to change. Anyway to address your points:

Yeah the fade looks a bit boring, I'm going to add a small amount of 
wispiness, though on that kind of scale I'd expect things to look fairly 
smooth, for example saturn's rings look near perfect from a distance.

I didn't google for any reference photos for this image because I want a 
more abstract/fantasy feel from my own imagination (I'm too lazy).

I've gone for a 5:1 ratio so that you have to scroll the image horizontally 
to see the whole thing. This isn't obvious at the moment because the test 
renders are pretty small... plus I'm not sure I'll have time for a really 
high-res render so it might not work in the final scene!

Secondly the scene is a 380-degree view, so in theory you should print it on 
the inside of a cylinder for correct viewing! From a story telling point of 
view this matters because the star at the start & end is literally the same 
star, the circle of life, etc... :)

However I am working on leading the eye better. I feel the left half of the 
image really struggles so that's what I'm focussing on. I'm adding some more 
rocks to the 2nd disc to tie in with the lava-planet, then I'm going to tie 
the discs in better with the cloud of stellar gas. I'm also messing with the 
overall background colours, because I think that can really help the sense 
of progression from left to right.

Thanks again for the criticism, it was very constructive :)

I'm probably being unfair.  Preview renders are called that for a reason.

Neat.  I thought of it as linear and periodic, not actually circular, but it's
painfully obvious in hindsight.  Actually, I think it was the shock wave / fire
on the left that threw me off since it doesn't show up on the right.  My mind
interpreted it as two slightly different things.  A perfect 360 degrees might
have made it more obvious, but you'd hate to cut into those nice effects.

I thought about suggesting something like the pillars of creation for that
point, but that would be a huge challenge to get right.

  Maybe this sort of effect would indicate some subtle distortion, like it's
circular instead of linear, only I don't know if that's what you're actually
going for:

No problem, but again, it's very good.  We just wouldn't get anywhere if we
patted each other on the back all day!

Hmm... I think that would be a whole image in itself, that would need some 
serious work!

It already has that kind of distortion, but I have deliberately avoided 
creating features that would make it too obvious (such as the cloud passing 
overhead in that photo). It also helps that my vertical field of view is a 
lot smaller (in fact it's 380/5=76 degrees!) so the most distorted areas 
aren't visible. IMO it's more impressive to make an image appear 
un-distorted when using a distorted lens, i.e. there's no way you should be 
able to see 380 degrees on a flat monitor without distortion, but I've done 
it :)

BIG version!

This is my back-up plan: if I don't have time for all the tweaks and a final 
render this weekend, then I can submit this one. My office PC is much faster 
than my home one so this took a mere 20 hours!

I think it's a pitty that, after all that work, all the detail is
hidden below the clouds and in the dark side of the planet. It doesn't
make justice to the amount of work put into the planet texture.
