I have submit a site template and got this feedback "unfortunately we found it isn’t at the quality standard required to move forward"

I am a new author in themeforest. I have uploaded a coming soon template. This was my first upload. But got “unfortunately we found it isn’t at the quality standard required to move forward”.
Can anyone please tell me what am i missing. My theme animation is optimized. Code is well documented and commented. Also, structured the code in a standard format. Used same font in all theme. I am just not getting where i have miss anything that can optimize the code and make it standard. Below is the demo url.
Demo Url: https://dreamed.space/spacesoon/
Any Suggestion please?

Hi,

I have see your item.You item is not ready for as a corporate/business platform there you can sell your item.Lots of issues like design quality,typography,font combination, spacing & alignment etc.

Thanks!

Thank You for taking the time to reply. Can you be more specific please? So i can change it and resubmit quickly.

There is lots of white space,spacing & alignment, typography,color combination.
You need to more study about themeforest quality item design quality, typography etc.

Okay I will and make sure not to repeat the same mistake again with white space, spacing, alignment and color combination. Thank You for the suggestion. Is using modal alright or should i change it too?
