Need Help! I got hard reject again!

After the first design being hard rejected one week ago, I created two new flyers, then I waited for reviews for another week. Just a moment ago, I received two emails saying that I was hard rejected again. I really do not know why, please see my works below, and leave me some constructive feedback, thanks.

Your work is looks pretty but try to increase the distance from the edges. Sometimes I get reject because I forgot to delete preview images, or must to separate files ( 5 colors - 5 separate PSD) or other. U can dowload some files from site & look at its organisation inside - that will help you

Thanks a lot. Your feedback is really helpful!
