My project doesn't meet quality standards. Please help me to understand the errors.

We have completed our review of “Countdown timer | Reflection in the floor” and 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.


I think that your animations countdown is too basic and very long time but you need add different projects and more ligh quality, you can add one project (10 seconds time) and add more projects differents projects… thank you.
