The bulk of my Inktober 2018 offerings came in the form of IPMDT panels, but on the “off” days I decided to follow the official prompts. I was determined to make it through all the prompts for the month, so for many of my drawings I wound up mashing several of the prompts together. I also decided I’d mostly draw in my sepia colored sketchbook using some of the many pens and brushes I don’t often use. Day 21: Drain. I came up with this one while sitting in the dentist’s office waiting for my kids.
