If you haven’t already, I would highly recommend checking out Dead End Thrills. The site is dedicated to crafting finely tuned screenshots through tweaking of various games and their engines.
Dead End Thrills is a site dedicated to the talent, passion and imagination of the world’s leading videogames. Any games, in fact, featuring art that stands shoulder-to-shoulder with the best the entertainment industry can offer. Historically, these extraordinary collective visions have been hard, if not impossible, to appreciate, trapped behind layers of technology and distraction. Developers, marketing people, PR agencies, journalists, players: few have shown the time or desire to strip those layers away.

The site was brought to my attention whilst wandering the internet for Skyrim related items. If you’re a Skyrim fan definitely check out their Skyrim images. If you’re not it is still worth checking out their other works.
