I've tried putting into practise a few of the suggestions made - There're still a few things I can do with lighting and shadow mapping and perspective, certainly, but I think it's a start!

Tried two different approaches to creating the cliffs - not sure which suits the style better, but I think they both get across the notion of cliffs

Thanks! Here's hoping the players like it. I just finished a mini-gazetteer for them (it's a new campaign) that ran to a few thousand words.

I'd like to bagsy the temple west of the Courthouse, please!

Here's Phase 2 - fixed the acne (thanks for the help!) and added phased relief for each layer of mountain as I construct them - composited, they're at least giving the notion that the mountain has varying levels. Lastly, added some houses for scale - mostly to see if they 'looked right'. I took your advice and added a cut-out from DD3 to illustrate where the interior of the mountain would be modelled.

That's amazing!
