About the construction of the cover for the New Millennium edition of A Wizard of Mars. Part 1: the planet.
A note for those interested in workflow: behind each of the steps illustrated above lies between 1-10 hours (on average) of time spent experimenting to find the right angle, POV, color, resolution, position in the scene, etc., etc. … as well as the extra time needed to render each scene to see how it really looks before making a final choice. Final renders, like the image at the bottom, normally take about 1.5-2 hours, depending on the final structure of the scene and what it contains. (Clouds, for example, can really kick up a render time if they’re sufficiently complex.)
