I like the instrumentation quite a bit! It has just the right amount of light-heartedness and joy mixed into it.
However, the piece felt overall static and didn't have much happening, harmony-wise.
The strings and music-box(?) dictate the rhythm, and they stay pretty much the same all along the piece. There's this part at the end that feels like it should be slower and lead up to the finale, but the rhythm stays the same. Consider mixing up the accompanying instruments; it will do miracles.
Thanks for reading!
