Why my item rejected please help?

I think that the track is too empty, there is not a fat filler like a pad or a synthesizer, I think that you need to add more placeholders and then there will be success =)

and too abrupt piano at the end, more tail …

thanks for advice.

There are too many items on the site without pads synths any placeholders. i saw too many examples on site that sounds empty. you are right about the piano.

The problem is in the mix
Piano, especially the low keys does not sit in the mix.
And you should mix the whole track again in my opinion

thanks for response
