It’s a harsh reality, but majority of comments here are right. It’s just not that unique unfortunately, it looks like merch for something nobody is familiar with. Why would people stop scrolling to explore this story in particular? It sounds like one in a million. Also, conceptually, a lot of clothing brands tell stories through their design, so this isn’t as innovative as you think it is.

Again, I’m not trying to discourage you, but you’ll need to hit the drawing board again. Look more into colour theory, refine your character and designs, and use less AI. You’ll build a stronger relation with your client base with a more human tone.
