unfortunately we found it isn’t at the quality standard required to move forward

I uploaded item to themeforest, item rejected, I want know what is the problem? here is the Message from Envato Quality team

Here my templates


I saw your item really it isn’t ready for Themeforest its looks like 3-4 years old design you need to improve your item quality(like design, typography, Spacing & alignment etc.)

Study and more research about latest quality about Themeforest.
