A stunningly outstanding piece of work, I can see why your elves feel justified in asking for a raise

I do feel there's a lack of resolution though - my OCD department feels a bit lopsided because there's no Bettererland to balance the Worserland Actually the whole place looks like travel insurance premiums may be somewhat elevated what with Wyrm Deserts, Pestplains, Dragon's Leap and Orsbang, where your 'orse explodes

Seriously though, the thing that strikes me about this is the simplicity of the palette. It has been applied to great effect and the use of saturation to emphasise and give the impression of depth adds stunning detail. Did you adjust the saturation levels afterward or did you choose the colours beforehand?
