Danny's Diner - Feedbag Challenge Comic Page 1 WIP10 (Patreon)

Once the lines are all finished up, colors can be put on fairly quickly.  All-in-all, sketching and inking take up 70-80% of the artistic process whether that be a comic page or a commission.  Flat colors and most forms of shading take up the least amount of time and can usually be done pretty quickly.
