For an exercise, I copied the composition of a photograph of a fighter on a carrier deck surrounded in catapult steam, and recreated it in 3D. I replaced all the elements with 3D Macross stuff and textures of my own creation (except for the gloves and the vests). It was good practice for lighting and composition skills.
Valkyrie fighter and clothes modeled or extensively morphed in 3ds max and ZBrush. Inspired by a photo from Reuters/Corbis.
