woocommerce project

Hi, I would like to ask questions to members about the final rejection by themeforest.
I designed a woocommerce website because I wanted to become a seller but when I refused, I did not explain why. that was my first question.
The second question is how is the home page built at the developer level? thank you for answering me please. because I got a little frustrated.
