Here are a few important tips that will help you sail smoothly in the world of illustrations.
Design for the User: One might lose himself trying to make stunning visuals. But it might become too unrelatable for the audience or the end-user. In this case, it will be better to start illustrating a basic sketch and add visual details to satisfy you as well as the user.
Avoid complex symbols: It is crucial to avoid any sort of symbolism that pertains to any culture or language in your illustrations. It is also wise to avoid any colors that may be offensive to your target. Do a brief study on the audience.
Follow color hierarchy: Use a minimal color palette of two to three colors. It helps the user to understand the hierarchy in the illustration better.
Spacing: Ensure that there is plenty of breathing space and as few elements as possible in your design. Remember that less is always more.
Use Grids: It gives you more control. It can help in abolishing the vagueness in your work.
Understand all these rules well as you learn and break them once you master them.
