You have to start somewhere.
For a while I have been doing concept paintings based on the game I am making. This is the sort of thing that might typically be done before any game assets get made or early in development. Since I am the one doing all the work on this game at the moment I’ll do it in whatever order I damn well please. In this case that means I have set up a sort of feedback loop. The stuff I do in the game informs the paintings and vice versa. It’s a nonlinear workflow.
One thing that is absolutely linear for me though, I can’t paint without first doing a sketch. Usually many sketches. So here is a set of sketches that I will be turning into a painting. Next week I will have more of a breakdown and I will walk through some of the process of making a painting.
