Logo Template Hard Rejected. Please, I need your feedback!

Hi guys, this is my first submission.
I read all the Envato guidelines but I can not identify the problem.
Can you help me, please? Thank you.

We have completed our review of “Coding like a Sir - 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.

Thanks for the feedback, I’ll try to improve it!
