I enjoyed the nostalgic feel of this piece, but like the others have said it does seem to maintain the same kind of rhythm the whole time, which makes the overall piece feel less dynamic. None of the sections stand out among each other, basically. I think this could've been fixed by changing the waltz melody (triangle channel) up a little. Something similar to this: https://www.youtube.com/watch?v=J_4wcJVX2BQ.
