In comparing your landing pad outdoor section from the top of the page to the more recent one, I definitely would say the orange lighting gives it a more (for lack of better words) grimy and hutt-like environment.
In terms of the Dxun skybox, I very much like the idea of a more prominent Onderon but in that screenshot it looked a little TOO sharp. You know what I mean? Otherwise all this stuff looks super awesome!! I very much like the subtlety of the changes.
