I sometimes study different animation styles and characters, this time the Disney show Kim Possible. I try to understand the style or character, then later see if I can remember recall it without any reference. You can 'learn stuff' by doing this..

I tried using chopsticks dipped in sesame oil to get some halftones, but it quickly bled over the lines as it dried, so I reverted to using soysauce, but that didn't mix with the oil.. a mess ensued. Digitally touched up the oil around her hair, but left the pants alone..
