The majority of the mix is panned too leftward. The original has the piano track panned to the right so maybe panning channel 3 to the right? I do however like how you centered the bass rather than have it panned like the original and chose to pan the flute instead. I did a little bit of fiddling and y7 sounded good for channel 3 but channel 1 overpowered it bc of the volume difference so I matched it (v170) and edited your volumes to this:
The end result sounded nice but I'll let you be the one to decide.
