Why my blogger theme is hard rejected.?

I am just curious what actually themeforest want from the authors. I have become familiar with the templates on the themeforest. The template designed is properly compatible with the google page structure tool..
The theme is even responsive and i think the design is quite good for the magazine layout in case of the blogger templates.
Is it just a fixation thing on themeforest.? So that only the existing authors will get selected and there will be no chance for the upcoming authors?

Even i doubt there will be any template providing such a admin panel.

My concern is just only to let know what themeforest actually want.!
