Who knows? I think that realism is not really an issue here. Personally, 
it does not strike me as too odd.

That might work indeed. I am almost sure it would. I shall test that 
asap and let you know. Thanks!

Alas! Doesn't work. Result in weird interference patterns.

Shame, it would certainly add something to the image if you can find a way of
doing it. Still it is a great scene even without the stain/slime addition.

Very nice.

I think the clouds look fine.
_If_ you wanted to play with them, I might add some of the reddish smog colors,
and / or perhaps "flatten" the nearer clouds so they don't look quite so
shell/sphere-like.

To be honest, I had to search for the girl in the render. (Hey, I'm getting
older...)  Perhaps consider extending a shaft of light down to point at, but not
touch her, or just highlight a portion of her leg, or the ledge to the side of
her - to direct the eye of the viewer to the solitary figure in the scene.
Maybe change the angle slightly or increase the radius of the crash grid to open
up a little space behind her and increase her silhouette.

Increasing the radius of the cage would be good - perhaps you could add a
dent/deformation or two to give the impression that it fell from the sky and
bounced once or twice before coming to rest?  The sphere itself looks great -
maybe the cage could benefit from some more "crust" or clumps, or dangling bits
of slime / algae / plant matter adhering from the impact - settling over time
and drooping down from one of the aforementioned dents...

I like the mist in the distance - do you think some mist or small curls of
denser mist in the foreground would add anything?

I think the lightning has a place - but farther in the distance.  Maybe with a
bit more yellow coloration?

Not sure what your thoughts are about the skeleton - too red?  Go with more
white and that sort of surface cracking/pitting?  Maybe a bit or two of crud /
slime on that too, and perhaps a little light filtering in from an opening in
the clouds?

I like the tree remnant in front of the sphere.  Maybe move it away a bit and
have its geometry and condition reflect its fate as the shattered victim of the
impacting sphere?

Great work - well beyond my current skill level!
I always enjoy seeing the amazing results and creative ideas that get
implemented here.  Thanks for the inspiration and sharing goals to work towards!

Thanks Thomas,

Don't worry, I intend to do this before end of month, I always like to push a
deadline to the last minute.

Controlling the colours is rather tricky in a multi media environment. I 
am still trying to get the white over-exposed part a bit darker, so I 
shall do my best with some reddish hues. The shell-like aspect is indeed 
something to look into. Not too extreme as it might suggest some kind of 
vertical whorls, but then again...

In following versions she will be better visible mainly because of a 
better flash control and behind camera reflection (just a dull screen 
but effective for filling in a bit the darker parts).

Hmm, no. In my mind time travelling is not equivalent to a cross country 
race :-) It has its own problems though like falling from the sky (the 
Roswell incident) or the equivalent of coinciding surfaces: coinciding 
objects (the Tunguska explosion) ;-)

Hmm, yes, that might be an interesting addition.

Maybe. In any case it is already yellow but could be more. Tests needed.

Just the image_maps of the models used here. Not really natural perhaps 
and could gain from some more texturing.

No. The stumps are the result of the wild fires following the Chixulub 
impact.

Thank you indeed. Glad to inspire others in turn. I am indebted myself 
to a large number of people here over the years and still, I have not 
yet reached their level of mastery.

Don't.

Lightning bolts are exactly /how/ hot? Some 20-30 kK, right? Color 
temperature (i.e. the visible portion of the corresponding blackbody 
radiation) doesn't get any more blue than that. And with the air being 
turned into a plasma, emission from electron energy state changes within 
individual atoms plays only a minor role compared to the thermal 
emissions from free electrons and ions.

Add to that that nitrogen, the most abundent gaz, tend to produce blue 
and UVs when exited. Next is oxygen whitch tend to glow red.

Indeed. However, I read somewhere that with distance from the viewer the 
colour becomes more yellowish 
http://www.ccmr.cornell.edu/education/ask/?quid=1271

In the image, I think I am going to use a more bluish hue.
