My first Item (template for coming soon in Bootstrap4) was HARD rejected - isn't at the quality standard required. Why?

Hi everybody, my name is Davide.

Few days ago I tried to submit my first item but this was been rejected and I don’t know why. The mail that I received doesn’t tell me anything about the problem, but only “…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.”

I feel sad because I worked for 1 month and now I had this bad news.

This is the link of the LIVE DEMO :

In the zip that I uploaded when I did the submission (so the complete project for the buyer), I wrote also a very complete and extensive documentation with many screenshots and pieces of code.

I don’t wrote anything about SEO, but my template is one of the “special” one because the category is comingsoon and not for a commercial product but for a generic kind of products, so the SEO part it’s not present. This can be the problem? I have no idea…

What are the steps that I can do to re-submit this Item?

Anyone can help me? Thank you very much guys.
Cheers, Davide.
