I submitted this happy vibe children music I produced and got rejected with the below feedback from the team. What do you think is my weak point?

Here is the music link:

Hi, Thank you for your submission.
But, this item does not meet the general commercial quality standard required to be accepted on AudioJungle, unfortunately.

With this style of music it’s so easy to go “over the top” with cheesiness, which I think you did. Mostly with instrument sounds. The piano sounds very cheap and digital. The claps shouldn’t be panned out to the side. If you used more unique modern sounds like the background music in Wii Sports it might be accepted.
