Playing with colour mockups
In every project, spend some time creating mockups or colour studies of your image in a separate file. Think about the mood and the message that you want your image to convey to viewers. After this, you should start testing all possible options to communicate your main idea. At this point, don’t worry about getting things well-defined – try to use very broad strokes and feel whether your colours, lighting and tonal values are really working well together. The most important part is to have fun doing it.
