Why is my logo template rejected ?

“Thank you for your submission. We have completed our review of “Pizza Logo” 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.”

This is a message i got on my second upload of the logo, what is the problem? I got al the technical issues solved and it still wont approve our files.

Can you please post common mistakes and what should we do?

Here are all the files we submited:
