Kazumasa Uchio is a Japanese concept artist and fantasy illustrator. Beyond that, I have little background information.
Uchio creates fascinatingly elaborate fantastic landscapes — full of curvilinear Art Nouveau inspired designs, glowing windows, luminescent plants and lots of other deliberate eye candy — inviting you to browse through them in a leisurely manner, as though a tourist, drifting through one of his fantasy worlds on a flying ship.
