Unfortunately ‘WordPress’ has higher standards in terms of aesthetics. As higher quality items become available in the marketplace, approval requirements will increase to maintain appropriate marketplace quality.
The one big problem of your item is font color. Yes, font color. Why are you choosing a base color for the body text which you have applied in your design already? Though your design is good enough, but it’s looking similar with other items which have released few years ago, so try to create something unique and creative bro and also try to gather knowledge about typography, spacing & alignments. Hope you will get your goal one day. Cheers.
Thanks for the constructive answer! Yes, indeed, he decided to change the typography. When creating the design was very careful with typography, because it is very difficult for me.
