I don't know why my files always rejects, I submit 4 different project, but never selected

I am tired of facing this problem, I didn’t know why my projects always rejected?

second project 5 Html page design
and now Html to WordPress, I purchased an HTML portfolio theme from the Envato market and I converted this template to WordPress, No self-promotion, no images, and nothing just clean code. please help me.

Ok here is the web site and password, please review
admin panel: http://design-programming.epizy.com/wp-admin/

Thanks, Advance

Without seeing demo links of the items that were rejected then it’s not possible to offer advice. You should share those here.

Presumably you had permission from the original author to submit a conversion and they had submitted a ticket ID with support explaining that?
