This song reminds me a lot about Moomin, the 90s anime especially. As a Finnish person I find that a good thing. I think it's the combination of the instruments chosen and the lighthearted melody elevating the sounds. May I ask what soundfonts did you end up using on the song? They kind of remind of N64 era instruments, especially the little arp at 0:20.
If I had to give any sort of criticism, I would say that I find the vocal samples sprinkled into the song a tad unfitting. But alas, they're used so sparingly that they aren't a real problem or anything.
All in all, this is a song I could very well hear being used in a show of some sorts, maybe even a game. You've shown a good understanding of simple yet effective composition and I respect the skills shown on display. Have a good day and keep on composing.
