It is pretty easy to create illustrations with simple designs. However, it is not recommended to make your illustration bland and boring in the name of simplicity. You have to keep the illustration simple for your viewers to remember it as the key is to make the design memorable for recognition. If it is simple and not complex so only then the viewers would feel a sense of association with it. I did not know about this notion until I worked with an illustration agency. I was able to learn new things about the realm of illustration and hone my skills accordingly. What do you people feel about the ever-changing trends in illustration design?
