uploading transparent PNGs to Elements

Hi,

I created and submitted a collection of a purebred cat isolated on transparent background and it got hard rejected.

I am wondering if I chose a right category (Graphic). Maybe I should send each item separatetely, not as a set ?

What are your thoughts ?

If it’s rejected already, I don’t think uploading them separately won’t change the results, you will be still getting the same rejection message
