Why my Wordpress theme hard-rejected

I have uploaded my WordPress theme and its hard rejected.

I am very frustrated. Please everyone give me some feedback.

“We have completed our review of “TuneUp - Auto Parts WooCommerce WordPress Theme” and unfortunately we found it isn’t at the quality standard required to move forward, and you won’t be able to re-submit this item again.”
