|Guardians of the Galaxy (2014) concept art by Justin Sweet|
Justin Sweet is one of my favorite fantasy artists and his masterful brush strokes always take his concept art to a new level. Sweet just published concept art on his Facebook page and they're amazing. They include alternate looks of Groot, Drax, Gamora and others.
Justin Sweet is a professional concept artist who's worked on big budget films like The Avengers (2012), The Chronicles of Narnia: The Lion, the Witch and the Wardrobe (2005) and Cirque du Freak: The Vampire's Assistant (2009).
