Conceptual artist, Justin Sweet (The Avengers, Green Lantern), has shared some more of his concept art that he created for Marvel's Thor: The Dark World (2013) and Guardians of the Galaxy (2014).
The Thor 2 artwork includes designs for the main antagonist Malekith the Accursed (portrayed by Christopher Eccleston), the Dark Elves of Svartalfheim and Kurse (portrayed by Adewale Akinnuoye-Agbaje).
The Guardians of the Galaxy artwork includes designs for Gamora (played by Zoe Saldana), Drax (played by Dave Bautista) and the Nova Corps. Plus, an unused image of The Badoon, an ancient and reptilian alien species that was supposed to appear in the film, but because 20th Century Fox owned the rights to them James Gunn couldn't use them.
