To answer your question Nicola, that's tricky, as I'm not sure either is how I would have framed or cropped the scene.
Also, I would have done some cloning out e.g.
In #1: the two foreground (fg) blurry rocks, the headlamp streak and the white triangles (etc.) on the left hand mid-distance rock. Alternatively, just crop off the two fg blurry rocks, then do the cloning, including an adjustment to the (now) closest one on right hand edge of frame.
In #2; the same white triangles (etc.) and the rocks that have fallen on the lower edge of frame.
Although not everyone likes to 'mess with reality' by cloning - and that's fine.
On balance, I think I prefer #2, although I'd crop say 10% image height off the top edge.
Hope that helps, Dave
