Hi there :)
The instruments and vibe work great! Casual and uplifting, perfect for a shop theme. Though, it feels as if either the reverb is a bit strong, or a particular sound is annoying me, as it sound like lots of notes are constantly clashing; I am not sure if that is the right analysis, but that's how it sounds to me. From 1:00, that is mostly gone luckily :). The song has a nice feel to it, and the jazzy instruments work great. I like it :D
