I like some of the vibe that's going on, I can see this being music for a hike through a forest with some characters in a game. I do have to say that the choral "ahs" don't really add to the cheerful vibe, and adds a different layer of mystery and apprehension. Not sure if that's the intended vibe, but it does clash with the harshness of those piano keys and I'd recommend some tweaking on those. Let me say that those drums totally slap though. Right at 0:19 I didn't know what was supposed to be happening, but it did add a cool rhythm!
There's a lot of repetition which could be solved by doing something with the piano most likely. I do like the strings that come in halfway, they add a nice airy adventurey-element, and then it returns again toward the end. I like that this is loopable, it does taper off nicely with the percussion, but the looping as it returns to the beginning could use a bit of work to smooth out the transition.
There is no description you've posted here with the song so it's hard to tell what the aim is with this piece, nonetheless I think it's a solid take at a videogame style song that just needs to be polished and varied a bit to keep the repetition from hindering the listening quality.
Keep it up!
