Help me to understand HARD REJECTED, 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

Thanks in advance for your time and really appreciate helping me out.

Last week We have submitted a PSD template for blogging called DeBlog, but after submitting on Envato they have rejected this theme with reason “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.”, & no specific detailed reason.

We are novice author but well doing in service industry. We tried at our good level to submit this item.
Now we want to work on a new theme but before that, we want to know the causes of rejection from Envato. we created 18 PSD file with help and readme files, 4 variations options. please let us know what you think. check below link for preview images.
