That was very good.
That sounded very clean with nice full notes and no buzzes.
One thing I noticed is that you played the half notes in Cucaracha as quarter notes. For example, in measure two.
If you count out the first two measures, it's;
one, and, two, and, three, and, one, two-three;
Where an eighth note gets half a beat, a quarter note gets one beat, a half note gets two beats.
I believe you did this in Allouette as well but I didn't actually check the scores.
