A quick and easy way to plan a composition is to draw a thumbnail of your idea. By thumbnail I mean a small drawing, simplified to the main shapes and elements that you’re thinking of including in the painting. I tend to draw thumbnails in pencil or pen, using line, as it’s fast and I don’t have to wait for anything to dry. You might prefer do it with shapes of tone, or using paint or ink. It’s a personal preference.
In the video below (link) I’ve done three thumbnails, one each as portrait, landscape, and square format, to give you an idea of how I’d draw a thumbnail. I’m certainly not going to win any prizes for the drawings, but for me it’s about thinking of the position of the face and ears in the overall composition, how much space there is around them. Studio cat Misty is helping.
For me there are three rules:
1. Work fast, don’t overthink it and don’t obsess about neatness.
2. Do more than you think are enough. I sometimes draw a page’s worth of rectangles in various formats (landscape, portrait, square), then challenge myself to fill them all. It’s surprising what can emerge if you keep going, and the ones you don’t use immediately can provide ideas for paintings at a later date or for a series. Often I do use my first idea, but by testing it against others I know that it’s a choice made from preference not from a lack of ideas.
3. If you don’t do thumbnails, be prepared to rework your composition as you’re painting, possibly multiple times.
Here are some other examples of thumbnails from my sketchbook:
