This is true for many things in life, but it is especially true when it comes to art and creativity. If something seems too easy or too simple to be pretentious, it probably is. The best way to avoid pretentiousness in your creative work is to be honest with yourself and your audience. Don’t try to be something you’re not, and don’t try to impress people with how much you know or how talented you are. Just be yourself, and let your work speak for itself.
