Reason for rejection of HTML Template

Need help from Authors,

I have submitted HTML template and got rejection by mentioning, “Unfortunately we found it isn’t at the quality standard required to move forward.”. This is very generic answer. Can you please help me to understand exact reasons, so i can correct myself for future.

Here is the link of demo, http://bit.ly/2Aktkr5 . Please review it and let me know your feedback.

Thanks in advance.
