Theme Rejected Help Needed

Hello, few days ago I submitted my first theme(Ghost) on Themeforest but it was rejected.
"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"
So I understand this is a hard rejection, and it means that there are some problems with the theme, can somebody help me identify what the problems would be?

Here is the demo
Thank you!
