General quality is good enough, but I think the first example is a tad bit too simple and repetitive. After all, this kind of corporate / children genre is the most competitive genre there is, so similar tunes are being uploaded a lot each day. I’d recommend to make sure there are enough details and intricate changes so that the tune is not just “create the simple structure and copy paste it ad infinitum”.
The second tune is also a bit repetitive, and the percussion sounds are maybe a bit too plastic sounding for this kind of chill tune. But it’s a close call as well, might have gotten accepted on another day.
