it sounds pretty choppy to me like when it switches it has a .05 millisecond and like the heys and the xylophone thing is off in some parts yeah make the notes go together better like try to learn some music theory some more. and I hear a lot of repeating going on yes it changes but for a lot of parts in the song it just repeats.
I liked the synths that you used, they fit together well
My recommendations:
the middle section could be altered a bit to give the song better contrast, and keep the listeners interested. The song's pattern is A A A but something like A B A might be a but more engaging
Some of the chords are conflicting, it sounds like you're trying to go for a minor key in the song, but some lean towards major, but some don't, at least as a listener that's a bit confusing.
There's a synth that joins in at
0:38
that doesn't really fit as well with the others, which provides a nice feel to the song, but its a little... scratchy? Its too rough for the rest of the song, consider altering it to stand out from the other synths but not too much
