Navigation Bars Rejected..what should I be improving upon ?

I had uploaded a set of navigation bars in which, of course, I had put a lot of time and effort.
Sadly, they were rejected and im seeking some feedback and advices as to why they got rejected and how can I improve upon it to make it an item that reviewers will approve.

here’s the preview image:

Imo the preview wasn’t as good as I wanted it to be, a bit rushed, but I don’t think this was the main reason for rejection.
Also the reason for the rejection was that it isnt at the quality standard.
Thanks in advance!

hi i think that presentation is something crucial, think about it, this is what will bring the first impression to reviewers or potential customers, in this cas this is a bit messy ,even hard to understand what this is if u do not read the dscription before seeing your item …

i think that these bars are too much in minimalistic style and that u need to introduce some originality some how some way
