The art is nice, and I like that it's not only about romance, and that the two protagonists actually regularly interact with each other rather than pine from afar. It's generally cute, and of decent quality, but by no means groundbreaking.
One point that's a little weird is writing Chopin as an adorable mascot type character with a demure Nadeshiko like personality. I don't know much about the actual composer, but it seems rather unlikely he was like that.
The other point that's a little disappointing is that it takes away from the protagonist's own accomplishments somewhat that she's motivated to play the piano in order to chase her boy, rather than wanting it for herself, though I imagine that's likely to change later. Still, it seems likely to focus on "I couldn't have done this without your help" aspect for the romance rather than make her accomplishments about herself.
On the whole though, if you're looking for cute, fluffy shoujo romance, It's recommend reading this.
