This has a lot of potential to be great but there are a few things. I think one problem is the contrast in dynamics. For example 1:26, that main sound is completely drowning out everything else and it's also very rough instead of like a smooth vibe so it messes up how the song expresses itself. There's also some odd note combinations from 0:13 to 0:55. It stems from that last note you use and the ones added in at 0:29. They kind of clash.
Overall I feel there is some work that could be added to make it a lot more fluid but it's really not bad
