Substance and storytelling go hand in hand. The relationship between the two is often what distinguishes a "good piece" from a "bad piece". Though the interpretation of art is always subjective, I strongly believe you must truly care about what you're working on for the audience to take notice. That's what I love about being a writer, you get the opportunity to dig into a story, find the component that makes it special and extrapolate it for the world to see.
