Hi, my track has been rejected, I need your feedback please. Thank you.
Hello! 
It does not sound live.
Musical instruments lack life.
But your track is quite musical and it’s great 
My advice, banal but, уou need to work more in the mix, and listen to more tracks of top authors in these categories. You need to practice mixing and mastering your music.
I wish you good luck!
Thank you for your feedback and your advice, I appreciate.
