PSD - Hard Reject Need help !

Hi Everyone, I have uploaded PSD But it has been rejected

Hello, the design requires great improvements still.

The main improvements you should make are:

  1. typographies, all related to typographical hierarchy and spaces and heights separations etc.

  2. The color definitely has to be reconsidered, set up a new color palette.

  3. The images try to check in biblotecas as photodune there are more improvements that you should make.

Improve on these points and then you can see an advance and in which fields still fails.

regards

Thank You for your advice.
But sir, I am really confuse for typographical hierarchy and spaces.
