I'm currently in the process of turning one of my smaller drawings into a large scale painting with a few changes in colour. Done on drywall, something I'm experimenting with-I still prefer wood although the surface is smooth it's difficult to maneuver as I prefer to work on the floor.

Drawn on outline

Current status-all first coats done along with most second coats, some colours need a few more, and outline and detail highlights still need to be done
