The Green Lanterns Corps are a space police force in the DC comics continuity. They are made up of every species imaginable, so I thought it would be fun to do some based on aliens in the cinema.
The first in the series is the heroic Optimus Prime, leader of the Autobots from the Transformers movie.
Update: After doing my Black Lantern I decided Optimus deserved a more complete setting than outer space, so I created Cybertron for him to stand on.
Optimus: Transformers screen capture and prodution still.
Cybertron cityscape: The Matrix: Revolutions scene.
Moon: Death Star
Floor: Detail of one of the alien ships from ID4
