In the waltz, which I really love, the accompaniment is much simpler and this makes room for a nice melody in the right hand. That is fantastic, I can imagine a big orchestra arrangement in my head. At some point in the middle, I feel your dad is getting a bit carried away with technique. He is doing some great runs that I can only dream of playing, but for me they don't add much to the emotion of the track. At the start it sounds so nice and romantic, I would stick with that.
In all cases, great music!
