The reason for project rejection (PSD Template)



Hi guys.

Please help me to understand the reason for the rejection, to continue to move in the right direction. My work has been rejected, the reasons I do not know, I would like to understand why?
I understand that the requirements for the quality of work is very high.

Screenshots of some pages:



Header section needs improvements etc Top bar and menus. It would look better if you reduce the font size of paragraphs.
