I finally broke down and bought a Wacom Graphire tablet a week or so ago ($75 at Best Buy, how could I resist?) and it's really cool. I've got a steep learning curve ahead of me figuring out how to contol the thickness of brush strokes based on pressure at the pen-tip, but it's awesome being able to erase "inks" so easily, or take a picture 5 or 6 steps back when I get in over my head. Heaven knows how many projects of the past ended up in the trash because of a goof I made just inches from the finish line.
Anyway, it's still easier at this point for me to do "caricatures" as opposed to "realistic" stuff, so with that in mind here's my first finished doodle. Be kind:
