Unfortunately we found it isn't at the quality standard required to move forward?

Recently I have upload theme first time on themeforest. I had created from scratch with 2monnth of hard work but after reviewed by them. They rejected theme with following message. “unfortunately we found it isn’t at the quality standard required to move forward, and you won’t be able to re-submit this item again”.

Can anyone please suggest what was issue or give me some information.
