Why my one page theme got rejected?

Hello Authors and Everyone,
I have uploaded a one-page html template. But it got rejected for not ThemeForest standards. Can you tell anyone what kind of standards are not followed in it. Please I really need help to resolve this.

impossible to tell from thumnails - what’s the demo link?

I have uploaded it only on themeforest but got rejected. So I am unable to show demo link. Is there any way to show demo links

If it is a HTML template then you have to host it somewhere online. If you haven’t provided such URL for the review that it was rejected without anyone even taking a look at your screenshot.

However just looking at your screenshots, it looks very generic and forgettable. You need to create something much more unique.
