Had a blast listening to this submission ! I had mixed feeling at first because of the chords, which I think are a bit much in the sense that they sound like you were trying to do polyphony, however they started to make sense with the rest of the instrumentation.
The drums and bass are super juicy, well mixed, well saturated and the song progresses in a very satisfying manner. I love that unresolved ending too. The only thing that really bothers me is the beginning with those chords, they sound really odd without the context and it really impacts the overall listenability.
Otherwise, I like how you represented the oppressive and massive athmosphere of the painting with your sound design and time signatures. Sounds like a chase in the abandonned shipwreck in the painting.
Good work !
