Need Help..! My very first item has been hard rejected, why?

Hi every one,
I need feedback and suggestions on my very first project, which has been hard rejected,


I don’t understand why? As I got reply :
After completing our review, we’ve determined that ‘Rocket blast Logo’ isn’t at the quality standard needed to continue forward with the review process on VideoHive. As the submission is too far off the standards we require, you’ll be unable to re-submit on this occasion.

This looks like a flash animation, Could have been a approved project 5 years before with Activeden.net, Files with these quality never gets approved, look at the popular templates in After Effects Category

No offence, Good luck

Thank you for your suggestion. I’ll improve my work quality.
I think flash or 2d animation is still popular and have that much engaging quality which was 5 years before. As “Ice Age 5” end credits are in flash animation (2d) which is latest movie.
& about quality…what is your opinion about this- https://videohive.net/item/rocket-logo/13606691?s_rank=1

Hello! Your execution and quality is way better than examples you’ve shown.
I think, you should remade ending and execution of logo. Maybe rocket should get way more acceleration in the end and with this ‘fly away’ and a light splash logo will reveal.
