12 Maintain the overall look of your initial sketch
Throughout your painting process, make sure you regularly refer back to the thumbnail of your image. It’ll help you keep everything in scale and perspective. Furthermore, I remain zoomed out of the scene while painting the illustration. The old masters used to assess their painting’s proportions by stepping away from the canvas. I’m doing the same, zooming out to see everything at once, even to the extent that my painting is reduced to the size of a thumbnail.
