Ruan Jia is a concept artist currently living in Quebec. Having formerly worked for Chinese developers NetDragon, his most recent gig was with Volta, a studio that specialises in providing things like art and world building for video game companies.
His art isn't just great by concept art standards. If I could print these off in a giant size, stick 'em in a giant wooden frame and hang them in my house, I would. They're like pieces from a classical art gallery, only instead of featuring stuff like picnics and men with large dogs was full of paintings about dragons.
