Rejected theme suggestions

Hi guys,
After many changes in my theme xlines i recently uploaded it but again fail and rejected.
Here is the rejected message.
Thank you for your submission. We have completed our review of “X-Lines - Responsive WordPress Blog & Portfolio Theme” 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.

I dont understand what is the quality standards for review team. Also in rejected message there is no explanation as to whether the problem is at the front end or at the back end.

I’ve seen many themes in themeforest library very weak design and poor content themes accepted.
Do you have any suggestions?

Hi.

Unfortunately your project does not have a premium quality, remember that this template will be sold here.

Think about it. Would you buy your template?
Knowing that there are thousands of free templates everywhere and much better designed.

The mistakes that are seen are their work are many, it is very difficult to rescue some of their design.

You have to become familiar with the quality of premium themes and start a new project.

It can be very frustrating to work so hard and not be accepted. But that is the ideal time to get serious about work, and soon you will get better results.

Best wishes to you.

regards

Thanks @TexTheme, i guess it will not be easy to publish templates here but I will continue to try it maybe next time.
