Here's my pear: One thing that is very tricky is pencil control. Like: 1) Shading a region and ending up with a clean rectangle without scribbly edges. 2) Shading an exact value. ... are both pretty tricky, and you can tell I kind of cheated the edges by drawing them, as otherwise I would get a blurry transition. Here's to improving fine motor control both in my wrist and my arm, haha.
