What a fun theme! Anyway there's three groups of terrains consisting of one rounded, one spikey and several almost vertical terrains sticking through the others. Train is by Emphigus, here in the Rendo free stuff. The Warren Truss Bridge was created in FormZ some years ago and updated in Modo. Plants from the Bryce the presets. Water by J.B. Allen from his "Seriously Real" mats. Moon is Bryce'a moon image appled to a 2D disk object. Illiuminated entirely by a custom HDRI matching the sky colors. No post except sig. Thanks for looking!
