This is an ambitious style that's difficult to execute, and I'm impressed you made this with only a few days to work with. There's a lot of composition in these 3 minutes.
There's a spiky texture to this that does feel just like the thumbnail image. If this were a human performance with more expression and dynamics, really accenting certain beats and bringing out some notes over others, I think it would really find its spiky texture groove pocket. I think the relatively flat nature of midi tends to make the ears meet each incoming note equally, making it sound more chaotic than it would be if the ear could latch onto those larger shapes and compositional ideas through phrasing and expression.
