To keep the style for the backgrounds consistent, but still divide the workload we established a pipeline for the backgrounds. Daniëlle (the other artist on our team) would do a rough sketch to block out the scene, after that I would do a second pass and refine the sketch, sometimes changing the composition a bit or adding points of interest. Daniëlle would then do a rough block-out of the colors for the scene and I would then, again, go over it and refine, add line-art and finish up. I also had to make sure the layers were clean and organized, so the backgrounds would work well with a parallax effect.
