I've been keeping a sketchbook for almost two months now, and I have the first month of sketches to share. But first, some artwork...
http://www.deviantart.com/deviation/24594079/ - Admit it. He's adorable. X3
http://www.deviantart.com/deviation/24593978/ - A weird Breloom.
http://www.deviantart.com/deviation/23995129/ - Yumi, a character from a future comic of mine.
And now, the sketchbook... most of these are original characters, with a few rare exceptions. (Kirby, Rock Lee, and the Jumpluff come to mind.)
