What a great place. Sun, sea and relaxation. I can imagine how much pleasure people got on Sunday morning listening to the puffy fortopean music. And I can imagine what emotions you feel when you see the positive realizations of people listening to your works. This is the best feedback that will definitely motivate :)
Positive feedback is indeed the most motivating thing. If I feel people are enjoying the time, and the music, then even nicer songs are coming :)
