Why my Personal template rejected?

I tried hard for weeks to design a personal template for sell in themeforest. After 2 hours from uploading my file they rejected that because of quality. Would you please check my demo and tell me why?
My demo link is “http://retrina.com/uone/” or click HERE.
Thanks a lot.

With respect, you’re still far away from Themeforest standards. This category is so overdone and only products who stand out are approved. You don’t have enough features (having 1000 variations for the same header won’t help). Study more, and learn from tutorials to be able to build outstanding templates. Thanks.

Thanks a lot for your answer,
Would you please tell me some of my mistakes or rules to make me better?=
