Puzzle: The Dreaming Tree

With its wonderful fantasy imagery and subtle colour variation, this is one of my favourite puzzles, so much so that it decorates the wall above my work desk. Reminiscent of Elven trees from Middle Earth’s Lothlórien, Vallenwood trees from Dragonlance, and Ygdrassil tree ships from the Hyperion Cantos, its winding steps, dwellings, and terraces are a calming, inspiring sight.
