This sounds like it would fit very well in an alternative soundtrack for a slower and more modern Mario game. The atmosphere from the strings is great, and I like the repetitive piano that calls back to the original!
I do feel a weaker sense of rhythm in this though, which a lot of Mario games do well. I think using quiet bass notes from the piano could do a lot in giving a sense of rhythm without taking away from the sense of space in the music. The synth bass does not have a strong enough attack to drive the forward movement of the piece.
Overall it’s a nice track with great ambience, well done!
