Drawing random pictures is fun and simple. Basically, your final poster will be a collage of images that do not necessarily go together in theme but look cool because you drew each of them in the same style. Once you come up with random pictures to draw, fill a paper with them, and you've got a poster of random drawings. Here are some ideas to help you think of random pictures to draw.
Instructions
1. Think of something funny or ironic that you've seen recently. Some websites of random pictures post a picture of a baby who has a funny look on his face and then the poster types in what the baby might be thinking.
2. Consider drawing a poster of different types of something. A poster of different animals or video game characters would make for a good random collection of pictures.
3. Try drawing different shapes with different colors. A picture like this would have a modern art feel to it. While the shapes and colors are random, it will look like a cohesive piece of work because you will only use shape and color in your picture.
4. Make some of your drawings overlap. This will give the picture a random yet planned look even if you didn't plan anything ahead of time.
5. Have someone help you brainstorm weird ideas. Each idea should have two parts: a noun identifying what should be in the picture and an action or descriptive phrase describing what the character is like. A zombie getting stood up for a date or a dog that won an Oscar are some ideas. The crazier your partner, the more creative your picture will be.
