This isn’t necessarily video game related, though there is a chance this art could be concept art for a video game I’m not aware of, but Deviant Artist Christian Quinot, better known as cloudminedesign, is an artist I’ve watched for some time now. His work his grim and gorgeous, and varies between dark fantasy and terrifying images you’d expect from a particularly nasty nightmare. I love it, and I think you will too. I’ve handpicked some of my favorite works of his, but for the rest — and there’s a lot of it — I suggest checking out his Deviant Art portfolio.
You can see more of Quinot’s work on his Deviant Art gallery.
