I can't get AdSense approval | Does anyone know a theme similar to this theme?

[RainDeath]

It's been two months since I launched my site. Initially, it was being labeled as having low-value content. Now, however, there is no specific reason given; it just says 'rejected' every day after I submit it for approval. Does anyone know the reason why? Also, does anyone know of a theme similar to the one I am currently using? See the screenshot here: https://prnt.sc/r65muw My site: https://mutanplex.xyz
