New author seeking guidance on item review

We are new to the Envato market place and are struggling to get our item approved for listing.
We have reached a point where we simply don’t understand where we are going wrong. I have uploaded the files here http://vrunik.com/kimaya/. The review comments we got are not specific and hence we’re finding it very difficult to conform to the Envato template standards. Request the community to please look into it and help us understand the problems. Thanks for your help.

These are the comments we received.

  1. Please label, group, and collapse all layers appropriately. example: https://envato.d.pr/nosqoD
    Our layer structure:http://vrunik.com/kimaya/screenshot/

  2. To improve readability, please adjust the line height of the following text elements. Ideally, line height should be unitless. Ref:https://www.smashingmagazine.com/2009/08/typographic-design-survey-best-practices-from-the-best-blogs/#6-optimal-line-height-for-body-copy
    Example(s): https://envato.d.pr/wCBS0a

  3. There are spacing and alignment issues in this item. Please make sure that all elements are aligned properly and spacing is consistent from section to section.
