Good vibe, for me it fit the post apocalyptic setting you were aiming for well!
Felt to me that you could've had a softer bit somewhere in the middle, where you maybe dropped out the sequence for a while, since for me the bright bell sound of it got a bit grating after a while, even if the sequence itself changed.
This one is probably just my personal taste, but I felt that the pluck/guitarish melody sounds could've maybe used a bit more reverb or just be a bit more distant sounding to not feel so close compared to the accompaniment and just help amplify the feel of the cavernous factory (still, just personal taste though 😉)
Nitpicking aside, good stuff!
