Yes I can, I think I posted my drawing somewhere over Hermit cave's thread a couple months ago... I've remembered My very first drawing Tablet was a Wacom Bamboo in 2008 after getting tired of using mice for coloring.
As everyone says I suggest you to take a reference and focus on what kind of style you after also start doing sketch a day or something to makes your hand be more easier to handle a pencil or pen.
bad_fur_day1: I'm only a moderate illustrator, but feel free to ask me anything you want. If anyone wants any help;
It's mostly done by refining, start with a light pencil, draw basic shapes like spheres and cubes in the general positions you want, refine the drawing with darker pencils. Thinking in the shades from the light direction is better than just using outlines, eyes are dark on the top edge but lighter on the bottom, not just a circle. If somethings looks wrong, rub it out and try again and again until it looks right.
Practice and practice and you get better at it slowly. If you want to draw figures you'll probably have to learn some anatomy, draw skeletons and add muscles and you'll learn.
Here's another one, probably better than the previous one.
