One of three huge skies made for planet-scale space station shard (featured as a matte if you mouse-over the abouve image). Unfortunately all the skies were combined with other terrain dmps and live action shots in the final edits rather than individual matte paintings or even comps. It leaves the feeling that they were clumsily integrated.
The brief was that the skies had to have a glowing quality, though not at all suggestive of a sunset. They also had to seem as though they were lit from below.
Original dmp size: 16000 x 4000.
