This is pretty cute. The design is nice and the music is pretty cool. (The simplicity fits the image, as it's really a music box) It indeed takes a while until the music repeats, that's too bad.
Your sprites seem to be too much based on regular art still. I'd suggest practicing with really tiny things. To be honest, this kinda looks like a drawing that was supposed to be three times this size and had little small details or textures, that was shrunken to this size,instead of something that was supposed to look like this.
Still looks pretty damn cute, and has a really sweet vibe :3
