I think you fell into the same trap I did, forgetting about the track being meant to be a shop theme, but I'm a huge fan of this track nonetheless.
The synth and trumpet sounds are super well chosen and generally the ideas are pretty creative, nice bit of panning as well. In my unprofessional opinion, I'd say to make this sound even more earthbound you could try to use silence a little bit more to break up the constant melodies, just to add that little bit of awkwardness. Still very impressive
