Help. Please guide me where we wrong to get approve. My theme rejected due to quality standard.

Hi,
I uploaded an item to ThemeForest, but the product was rejected, I want to know what the problem is. Here is the Message from the Envato Quality team:

Thank you for your submission. We have completed our review of 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.
We appreciate the effort and time you’ve put into creating your item. And we’d be happy to help make sure your next entry will meet our submission requirements.

I would appreciate your help to know what the problem is.

Thanks

Hi, There is no premium quality. Outdated design. I suggest you can go to check trending items.
