Waltz challenge- No.1 C major

Hiu, I decided to do a "waltz challenge", the thing is composing one waltz per every week of the year without getting monotonous, in all 12 major and minor tonalities, at the end I will like to do a waltz for at least 5 instruments.

Here is the first week, waltz in C major, actually it was composed in 3 days.

Good luck!

This waltz sounds like "música de salón". i like it. The middle part loses the melodic feeling a little bit but that's nice.
