Couple of months ago, I made some concept art for a game I've been working on for a while that I shared an in-game screenshot of a while ago! I'm not sure if this counts as something really refinery-ish, but anyway, have a short video of how I made some of my characters. The first one, I sketched on paper and then lined + coloured digitally. The last two were done right on the spot. This was a few months back, when my art was still fairly gross, but there it is!
This was livestreamed, so sorry for poor video size + quality.
