I don’t understand what the quality standard is. Files are regular, the codes are well interpreted, README.md file added. Is there anyone who can help?
This is my template https://air-con-and-tec-service.netlify.com/
I checked your template design. You really worked hard, but the design does not have any artistic elements. This is very common and simple item in recent time. So, themeforest might reject it.
For quality standard means, your item is not suitable for marketplace selling.
