Feedback for my Rejected Track

Hello!

I have just started doing stock music so I would be very thankful to have some help!

I have been writing and mixing one song a day for one full week and I decided to upload them to AJ to see if they would pass the review process. They didn’t, which I found pretty normal, so I would like to know what you guys may think is the main reason. Starting with this song: https://soundcloud.com/jtc_music/background

To my ears the things that fail the most are the kick sound, the lack of melody, the way the piano is played (seems pretty fake) and the boring structure.

Which do you think are the main reasons it got rejected?

Thanks.

Hi! You answered your own question!) Sounds, arrangement and mixing is the problem here.
