Game World Design

Some things I've been looking at with regards to the game world and creatures within it.

Deviant Art
Since this thing isn't letting me write in between pictures, I'll do it all here.
1) The colors make it seem really lifeless and broken - dispirited. This is probably too recent of an "apocalypse" for our setting.
2) The vivid colors make it seem as if nature has slowly been consuming the old civilization, still not old enough though.
3) An example of how nature grows over old ruins.

Overgrown - RathmianDeath

Shanghai Ruins - Jenovah-Art

Overgrown ruins - TheRenART

World of Warcraft - Cataclysm
Same deal as above
1) Some ruins - rather charred landscape and a really big tree.
2/3) How could the creatures look like? Not necessarily cute fluffy bunnies.

Ruins (Mt Hyjal)

Volcanoth

Shale Spider
