Theme Submission Rejected - Need feedback for Improvement

Hello, my first submission got rejected saying ‘it’s not up to the standards’. Can I get the feedback for my demo link as to what should be improved so that it will help in my resubmission?
Thanks in Advance

Demo: Dashboard - Yashuss Unlimited - Bootstrap 4 Modular and Demographic Dashboard

Hi, look at the latest approved dashboards and you’ll eventually realize that you’re still very far away from the required execution. The design is non existent, there are a lot of bugs on mobile, weak typography, spacing and alignment issues. Having a dashboard approved nowadays requires perfect execution, originality and technical quality. Iam affraid you’re not there yet. Daily work and practice is the key.

Good luck.
