@Sessioni Well when I started brainstorming my paint scheme 18 months ago, I decided my orcs are from an area much like Durotar in World of Warcraft, so have painted them in sun-baked colours and based them appropriately reddish brown to match my inspiration below:
In this area nothing much grows but cacti, there are also a few tufts of dead grass. This is where I imagine my savage orcs roam, hunt, make their crude weapons, beat each other and rally for war. Here are some cacti I found (just eBay search 'model scenery cacti' if interested):
The night goblins dwell in the caves which line the many hills in this area. There are also pools and isles which are filled with small forests of palm trees and life, which is where I imagine my to-be-painted forest goblins and their spiders roam. Here are some trees I found (again, eBay search 'model scenery palm trees' if interested):
I'd paint these trees myself as I'm looking for a better looking green then the flat green that's fresh out of a mold.
I'm thinking of doing everything but the forest goblins with small tufts of dead grass and some cacti here and there. Maybe a random palm tree unit filler here and there too to tie it in with my forest goblins, which I'm thinking of basing with a lot of mini palm trees and big palm tree unit fillers to emphasize that they're forest goblins. I'm still unsure though so am looking for opinions.
