This definitely fits the coldness that one might feel in an ice cream town. Space between the lowest and the highest voices is a good way to achieve that goal. Your melody has great voice leading and is easily singable which helps with catchiness. I find it interesting that it starts out minor and dirge-like but ends with an implied major cadence. One observation that I made is that when notes are clustered in the low bass range, it can sometimes be difficult to pick them apart and can run the risk of sounding muddy. I think the intentional choice of lowering the bass to add separation works well for a cold theme. Overall good work and thank you for sharing!
