Look at references
When painting an environment with recognisable elements such as man-made structures, it’s important to have plenty of references to hand. As artists, you should be able to identify the right images to help you to create your own original compositions. Finding the right photos and references were almost 60 per cent of the job when I was working on films as a matte painter. Once you have a manageable collection of references and are able to quickly select useful elements, your painting process will become noticeably streamlined.
