Rejected My Item in ThemeForest

Hi Everybody,

I uploaded XD Template on ThemeForest after 2 days got mail that my item was hard rejected but Themeforest reviewers did not provide any information, they sent a standard text when they make hard rejected.

I am very interested to know what the problem is.

Demo: Adobe XD

For earlier thanks to everyone who helped, I will also be glad to constructive criticism
