We can all agree that art is subjective. However, there are some things that are universally acknowledged to be detrimental to a composition and having a good composition directly affects the quality of an art piece. Of course you are always free to take full advantage of your creative license as an artist and it’s up to you to decide whether you want to break the rules or not. Regardless, it’s always smart to take design principles seriously and to take on a thoughtful approach to your work, especially when you’re still learning.
