I wanted to have a new promotion artwork for the Wormworld Saga for a long time, but never managed to find the time to create it. In May 2019 I decided to start working on the artwork on my weekly Twitch streams. That way the painting process got divided into 2-hour chunks, spreading over 5 months. Since I started every session with a fresh eye, I went through quite a number of iterations and the whole process took a pretty long time (around 50 hours). But I think it was worth the effort and giving it that time definitely had a positive effect on the outcome. This artwork is probably one of the most carefully balanced compositions I've ever created. I've also posted a GIF that skips through the results after every 2-hour session.
