Why is my item getting hard reject?

My theme has been hard rejected. Looking for any feedback on how to improve my item. This is link here. Soltrin - Solar Panel & Renewable HTML Template
Best regards,

Sadly it’s too similar to many existing themes and it doesn’t look unique - I’ve seen very many similar html themes/templates that look almost identical. In an expanding and sometimes saturated marketplace, you need to think outside the box and do better than what is already on the marketplace.
