I think you should be proud of this, it sounds really good! I think the mix is fine, it brings out the right instruments (the glockenspiel mostly) while keeping other harmonic instruments very well audible at a good volume and at the right frequencies. The song itself sounds very magical and almost lullaby-ish. The melody is very calming and drowsy, and evolves through the whole piece into just a beautiful thing. And the end is really pretty, where it feels like everything just comes together. Great work, keep it up!
