[Hard reject] Feedback needed - Help please

Hi all,

I just got a hard reject on my theme and the email message I received does not state the reasons. I am posting the message I received below. It sounds very general and hard for me to understand how to improve. I would really like to understand some more specific reasons for the rejection and most importantly how I can improve the theme so I can resubmit it. Can someone please help me with specific feedback? Appreciate!! Thank you!
