Pretty version here.
Quells, the developer of the amazing action/adventure/RPG Phoenotopia asked me and a few other artists to have a crack at developing some prototype areas for the sequel, so this is my attempt!
In his own words:
Earth Dome - The Collectors built a small replica of Earth in which to house the captured NPCs from the first game. The Earth biome is a dense forest with thick trees, swamps, and even bigger frogs. The collectors attempted to recreate the forests of Earth, but have created something closer to the forests of Earth's prehistoric era. Creatures grow to a more dangerous and unnatural size - giant bugs fill the air. The forest is also wired with cameras and radars - equipment the collectors use to monitor their captured species. The biome is a mixture of nature and technology - it's not unusual to find the occasional metallic tree or radar and camera equipment.
EDIT: Yes the background is very lazy and unfinished. If this job goes through I'll do a proper background.
