Nice work, I like the waltz rhythm and the flute melody at the intro. It makes me think of a fancy European dinner party. The middle section entered somewhat abruptly and it was kinda the last thing I'd expect to hear from such a happy melody from the intro. The harp and low plucking strings remind me of the Hitman: Blood Money soundtrack (not that it's a bad thing). The transition back into the waltz was executed greatly. Not a bad job, the instruments all sound very realistic. Keep up the good work!
Please contact me if you would like to use this in a project. We can discuss the details.
