Feedback on rejected song

Hi guys. Can you be so gentle to give me some insights on why this has been hard-rejected?

“This submission does not meet AudioJungle’s commercial production (samples/recording/mixing/mastering) standard, and its commercial composition/arrangement standard, unfortunately.”

I’ve spent an entire week analyzing the most common structure on the Sentimental Cinematic genre, the chord progression used, the more common instruments and so on.

For this track I’ve only used EastWest Gold libraries, which should be decent enough; I manually humanized every single note giving them different velocity and tempo values; and finally I let a professional engineer do the mixing and mastering just to be perfectly sure.

I literally cannot do better than this. And I’m really starting to lose hope on Audiojungle.

There is no effect of the room. the background needs to be farther than the basic sounds for example the conversation of the speaker. look for the lessons about the reverb on YouTube.

Piano hurts your ears. The lower mid is not stable (pipe). Don’t be afraid to add a large hall reverb. It’s a great idea. try to redo it.

Forgot to insert “watermark” removed the previous version has now uploaded a new track is not displayed. all for the convenience of people…
P.S. Do not waste money on “mastering”. Do it yourself. The engineers doing the track as the main element. “Aj” music is a secondary element in projects. It was something I understood.
