For Lina’s interactive harmony study, I think it is really clear for users to play with instructions listed on the bottom of the sketch and the visual design of the sketch is impressive at the first look. The interaction is very various with pressing the three stars and different keys to change the scale of one track and also adding human sound into the melody. The final melody made from the sketch is really harmony with each other and suits the entire concept as the playing cards and clown laughter well.
For future development, I think that maybe changing the interaction way of clicking on the stars to interact to something more integrated into the sketch and natural for users to click. Besides, the sketch is really fascinating with the interesting concept and surprises me.
