Please help. My shopify theme hard rejected

Hi there,

After a long wait, I received a response from themeforest about the themes I had submitted before. And the result is “unfortunately we found it not at the quality standard required to move forward, and you will not be able to re-submit this item again.”

https://occasion-demo.myshopify.com/

It’s my first submission. Can you please give me some feedback?

Thank you.
