Nice work Nico. I like the "unusual" camera work, as we often see a fly-through like camera movement.
What I miss is a tad bit of cloud movement and brewing, as they look very static without anything happening.
As you're a very experienced TG2 animator it might be useful for others if you could post your render settings for this animation?
Ok, every project requires specific settings, but there's also often a bit of overlap, so it still can give people a figure.
Also, did you use a heightfield for the terrain?
(I suppose using a heightfield with fractal detail added (via the heightfield shader node) is easier to animate and render without artefacts than a pure procedural terrain).
Cheers,
Martin
