Help me understand why was not accepted item

Listen, please.

Audiojungle rejects each item. I can not understand the reason. What’s my mistake? I received such a letter:
Thank you for your submission. We have completed our review of “Summer happines” 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.

Here is the comment from your Envato Quality team reviewer:

This item does not meet the general commercial quality standard required to be accepted on AudioJungle, unfortunately.

To understand commercial stock composition, arrangement and production better, please read the following article http://enva.to/6D-sd

We appreciate the effort and time you’ve put into creating your item. And we’d be happy to help make sure your next entry will meet our submission requirements. Here’s our advice:

Visit our forums and ask fellow authors for feedback. Our helpful community will be glad to lend a hand.

Check out this Help Center article to understand why and how items get rejected.

Remember you can get help, in the form of tutorials or skilled professionals, on Envato Tuts+ and Envato Studio.

Thank you in advance.

The mix needs a lot of work.

What exactly is wrong?

Composition/arrangement is cool, but it’s kinda “out there” for this market place. It’s quirky and unique and I like it actually but if you’re trying to sell here you kinda need to study what is working/selling recently and make sure you “fit in” :stuck_out_tongue:

I agree with @Manriquedelara about this mix as well. It’s pretty thin, the balances are off in a lot of places and not a lot of low end going on.
