Please help: Need a feedback on hard rejected item.

Hello Authors,

Recently I have submitted a My first WordPress plugin but it’s hard rejected. In email reviewer specified that unfortunately we found it isn’t at the quality standard required to move forward.

I am now going to make more design changes, but still expecting some feedback from different author.
