Hi,
About the sound: to me the piano sound is to wet, to much reverb.
Concerning the composition, this track sounds to random. There is no singable or memorable melodies and the harmony sounds completely random. Try to make a simpler melody you are able to sing or whistle and then try to harmonize it with chords in the left hand.
I’m afraid this track has no chance of getting accepted.
Good luck with the composing and continue to post here to get feedback and I’m sure you’ll progress
