found solution to my problem, you can delete this post. - Thank you.
are these yours tracks?
Yes. They are my tracks.
Hmm AudioJungle isn’t a classical music library. It’s a stock for video creators focused especially on a short commercial forms. That’s why I can imagine reviewer who wanted to encourage you to make the arrangement more “commercial” than “original”.
BUT those pieces are SO famous. Actually it’s even hard to imagine them in modified versions… And a lot of video creators are seeking for those famous arrangements. So the “arrangement reason” is incomprehensible for me.
And one more thing. You’ve made huge and great work, especially with Bizet. But I would try to exchange few libraries for better quality and more natural sound. And I would definitely choose different, more natural piano for Bach. Probably that reason was also important for the reviewer.
