I can't show the final here, as 1. NDA, and 2. very big!
But the result is stunning (if I may say so myself). Rendered at 0.8 and AA8, with soft shadows, at a resolution of 8400px wide, and back within a few hours from Pixelplow. Same with the other 2 renders for this book; Glacial and the Primeval Forest scene. Can't show them either.
So here's a thumbs up for Pixelplow; it really is worthwhile to send your stuff up, especially if you have a lazy machine, or only one fast one (like me). Before stills were difficult, because the GI prepass couldn't be done by them, but now nothing more is needed than a good file, and specified what you want to get, in the output image file name. Super!
