Assorted Weekend Doodles

I doodled a lot this weekend. All of these doodles are me practicing various aspects of things. I'm trying to see what I need to improve. So far, it looks like I somehow have more talent than I am able to use in a full drawing...I guess figuring our how to maximize my potential is #1 priority then. #2 Priority is working on people faces. By now, I have everything else of human anatomy (yes, even the hands) down pat, for my level anyway. Not including feet, which I am working on and don't appear much anyway in my art. Two of the doodles were done in pen at a friend's. This was my first time (at least professionally) drawing with a pen, so the other drawings were terrible. I love drawing eyes though...

From left to right: A hand in a glove and just a plain hand (the non shaded version), a crying eye, a zombie that was intended to be me practicing general anatomy including clothing wrinkles, a shaded shirt that was me practicing clothing wrinkles (somehow I know how to do them even though my drawings almost never include clothes), a balloon, a very shaggy canine leg and foot (3 toes because I'm lazy), a weird flat creature head with markings, a cute blushing fur person, an awesome shiny arm, and a row of awesome eyes.
