Worthless Finger (2.5" x 2.5")
If this picture were in a "how to draw" book, it would have a big red X through it. You shouldn't hold your pen like this, unless your index finger is out of commission.
Since I broke my finger, I've been drawing a lot of complex, instantly recognisable objects--hands and feet, in particular. I am doing this because if even one tiny line is out of place, they look completely wrong. I can therefore measure my progress quite easily.
So far, there always IS at least one mistake; one twitch, one tremor, one miscalculation. When I can draw a perfect foot or hand, with my index finger pointing uselessly at the sky, I will consider my drawing hand rehabilitated (well, to the extent one can do, when an entire finger isn't working).
On the bright side, my handwriting has actually improved, because of this catastrophe. I never used to pay much attention to it, and it was a disgrace. Now, it's mostly legible.
