Artist Jesse van Dijk has done some of Destiny's concept art, including the Citadel. He's just now posted some of those Destiny images at CGHub, but and there's other stuff on his tumblr to check out as well.

Freelance artist Kekai Kotaki has posted some of the concept art done for Bungie's Destiny on tumblr. Be sure to watch their tumblr for future imagery.

Polygon has a story about artist Joe Cross, who's done concept art for Dead Space 3 as well as for Bungie's upcoming shared world shooter, Destiny. That shot of the Pike speeding across the desert? That's his. What's more, he's doing other art for Destiny as well:

"I'm also doing a lot of the in game graphic design for Destiny," he wrote. "Graphic design is a passion of mine and an aspect of art that is under-valued or under-utilized in video games."

I've set the first sixteen images of Destiny concept art to the Destiny music track, "Eighth" by Martin O'Donnell and Michael Salvatori to create a Destiny Concept Art Slideshow.
