Shadows combine with light is something I do enjoy exploring through my experiments of photography. How about if it's used on another medium like digital art?
Searching for good inspiration for you guys I ran into the extraordinary work of Japanese artist HR-FM (that's his artistic nickname. His real name is Sugimoto). His work is pretty awesome and stylish.
Below you can see some of this pieces! Gotta love his style! These are very unique, and for more of them you should visit his portfolio at DeviantART! Tell us how do you like these! I'd love to know. Cheers. ;)
