Rejected! I need your help.

I got a reject for this track. Please tell me what am I doing wrong?

It seems to me that everything is fine with the arrangement, there is development, transitions, a melody. I think the matter is in the unsuccessful selection of instruments and timbres. Some sounds are outdated and not suitable for modern music, mixing does not reach the required level, the piano is too loud. Synth playing the main melody could sound more interesting if you work on it. Use sound references

Thank you for the comment.
I will edit it according to your advice. And I submit again.
