Don't stop posting sketch dumps. I've always loved seeing sketches from great artists such as yourself. They give insight into the process. They're further and closer to the artist's vision at the same time. They're an incomplete idea, but they are the very first materialization of that idea, and let you see the idea while it was fresh, and not left to stagnate as ideas often do to the point that the artist loses grip of some underlying element-- intrinsic malleability-- in a piece of art during its production and is unable to see it for more than the details that s/he has spent focus on for so long. Sketches are more organic.
I may not have said it enough, or at all in fact, but I am consistently enthralled by your lineart and sketchwork. Remind me to become independently wealthy so I can have you draw all of my doodz I've made up in my head.
Heh, some of these are OLD sketch dumps... XD It's weird seeing some of your more "cartoony" stuff, because all your art I've seen is pretty realistic.
