I am SO in love with this!! It's people like you and pieces like this that are really spurring me on to finally get my butt in gear and do more doodling. I mean, it's just FUN. There's nothing hard about it, you can let your imagination go crazy, and it's a brilliant lesson on composition and balance.
To get back on topic though (XD) you've done an incredible job with this! I plan on making a group on here for all the doodlers on shadowness, hopefully you'll allow me to add it into the gallery as a feature! =D
