This is the most serene of all the Pinball cities I’ve heard, which is a nice change in pace. I like the addition of the bells since that is the type of sound I associate with pinball - I wonder if doubling the sound up an octave or two would even further enhance that effect! The percussion also definitely fits the pinball vibe. I like your melody in that it is unique and interesting while being singable, though I did not end with it stuck in my head. Something that may be helpful is having a shorter segment of melody that plays, then after a space plays again in a different instrument or only slightly differently. Repetition in music is a delicate balance so you don’t want to sound too repetitive, but it's so interesting that our brains are hardwired to like or enjoy something more if we think we’ve heard it before. Great work and thank you for sharing!
