This is a neat little track - respect for putting this together in one night. So I have a couple pieces of feedback after a couple of listens:
1.) This track could really use some bass, or any kind of lower frequencies. As others have mentioned it's fairly thin, which think kinda hurts the impact of this piece IMO.
2.) This may be a matter of taste and personal preference, but overall I think the tone of this track could've been darker to better fit the theme of the jam. When I listen to this I hear this being more fitting for a shop or forest theme more-so than a scrapyard/junkyard/dumpster fire. I think if you change the key signature of the track it might be a better fit for the theme IMO.
Just my two cents, keep up the good work :)
