Mystic Forest This is really one of those things that you need to see at full size maybe even download it and zoom on it to see all the details, each quadrant practically a drawing on its own, and yet all part of one big and incredible picture, psychedelic and surreal but also organized each thing connects perfectly with the other.
Of course this goes to favorites, what is more makes you wonder if this great piece had color would it be even more awesome? i have no idea i myself like B&W too much to imagine it getting better than this.
