The motif in this is great, I could see this motif used in a modern Mario dungeon/boss fight. I wish the instrumentation you used right at the start was used more throughout the piece, it sounded really funky!
The dynamics of this sounded really good for most of the track, I also like the use of stereo in this. Some parts near the end sounded like they were fighting each other in volume, it made it hard to focus on the actual melody of the piece.
Overall well done, you did a good job crafting an idea that fits the theme when the original is so iconic!
