Why does my project was rejected


Some time ago I added your project Portgal (http://nihonscripts.com/patti/) to codecanyon. I got the message “In order for submissions to be considered for sale they must be of high aesthetic and technical quality, unique to our library and cannot be in violation of Envato’s policies.” Recently I browsed codecanyon and found a plugin that has fewer options than mine: https://codecanyon.net/item/gridzy-image-gallery-grid-for-wordpress/15138026?s_rank=1 and yet as you can see was adopted. What is the problem?
