Starless Skies: Downriver city

These are concepts and researchs i made for my Starless Skies animation project. The story takes place in a generation spaceship, an ark, to reach an exo-planet called Oiké.
The spaceship itself was carved into a metalic asteroïd of 180 kilometers long. It caries a whole ecosystem in order to terraform and the planet before human colonisation. The story begins at the end of the journey while inhabitants start to fight each other and cause a disastrous ecological chain reaction.
