It is at the moment Ulco, I've got two suns in this, one lighting up the atmosphere and casting shadows, the other much lower strength ignoring atmosphere to help light the landscape. It's kind of the mood I'm going for I guess. I thought I should see how the scene would be lit with this sort of cloudscape to see how the colours react, and as my textures are quite editable, I can adjust areas if they need it.
Some more work on the atmosphere and trying to resolve reflection quality, which is still a bit noisy.
