Several days ago I've finished a personal work called Wolds Collide which represented a battle between two opposing races : a mechanical one and an organic Ent -alike forest creatures.

Anyway I decided to further develop this idea and make 2 more stills as each one represents one alternative ending of the conflict .
So this is the concept visual for the second still in which the mechanicals gained a total victory , devastating the land of the forest creatures.
Mechanical Plague Spreaders are poisoning the ground to prevent the remaining forest creatures to reproduce themselves while Moisture Drainers are collecting the last recourses.
