Yes, I also think it's better in every aspect... The closest reactors flame was
of a nice color but its shape was too geometric, best to see the contrasted nose
of modules... I keep looking at the picture and of course see new details to
pick:
The furthest planet (rocky one on the left, don't you think it's pattern is too
regular?  I haven't used it much yet, but I would try the warp feature of
pattern modifiers, to give it a more cahotic look... And about the lighting
again, its too strong and flat: I think considering an ini file or command line
launch with display_gamma of around 2.2 or 2.5, if you just put all colors in
srgb and assumed_gamma 1.0 at start of globals (only the output image file
should be put back to 2.2 in gimp or whatever, after render if the final viewing
app shows it bad... But png probably wouldn't) Here is some tips for adapting
old scenes to new gamma maybe you've seen it already:

This will allow you to use and actually take enourmous advantage in such a
scene, of inverse power law (new in POV3.8 and the most realistic), for every
light :
fade_distance 0
(requires  #version 3.8 directive at very top of the file)
Attenuation for the lights is never linear in reality and thus you can choose to
 dim those main light with more control maybe lower or more focused angle,
letting radiosity kick in, especially if you put the deep space tone the darkest
kind of blue you can get instead of pure black. you'd get a less dark shadow but
still bigger contrasts inside of these penumbras > richer tones used overall.

I really enjoy the atmosphere of planet on the right.
And now I see the whole tree populated area inside of the donut, lot of work,
it's awesome! This would also show better if environment light outside the ship
gets lower! please please ! try it :-) One last detail, as much as i love the
crossing streaks of background white stars, having them smaller would do them
good. (The color values can go higher than 1.)
