Soft Rejected! what should I improve?

Hi everybody,

I am a new author on Envato. Previously, I submitted an item on themeforest, which was, finally, approved after 2 to 3 soft rejections. But I could easily guess from reviewer’s feedback what should I improve.
Now I submitted my second item, which is also soft rejected. The feedback I get is:

  1. Parts of your design are either difficult to read or have contrast
    issues. Please make sure all sections of your design have adequate
    contrast and all text is easily readable.

  2. The overall hierarchy of this item requires some additional work.
    Focus on better defining which areas of this item should demand more
    attention. http://webdesign.tutsplus.com/articles/an-introduction-to-hierarchy-webdesign-14947

  3. There are spacing and alignment issues throughout this item. Please
    take a moment to make sure that all elements are aligned perfectly and
    everything is spaced consistently from section to section.

  4. The typography needs improvement.

I can’t easily understand what are the things I have to improve. Can anyone give me some feedback please? This is a demo URL

Thanks in Advance,
