My item was rejected, does anyone give me feedback on how to improve?

“Thank you for your submission. We have completed our review of “CodeHamper-Kit” 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.”

Is it just the home page and login/register pages and that’s it?

Also, your header content is not vertically aligned and the " We seek the best" wasn’t obviously tested on a big resolution (like 2560x1440 or more) because it appears broken.

But even if you fix these two issues, you have a freebie item level of quality at best. There is nothing premium there.
