My item was rejected, i need feedback

I recently uploaded an item to codecanyon. But it was rejected and such an e-mail.

Thank you for your submission. We have completed our review of “Grand Presenter - Scroll Effects” 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.

Here is the feedback from our review team:


It seems that similar functionality is already offered by other items on CodeCanyon and the web. To be considered for approval, it would be beneficial for your item to have unique features that set it apart from what is already available. Thanks for understanding.

Demo : http://103.13.210.215/grand-presenter/grand-presenter-demo.html
Do you have any suggestions for this ?
Thanks
