The piano is a little off center for the entir track, but at the 0:17 and 1:27 mark the piano goes off center even more so, and is louder in the right audio track, which is very unpleasant to listen to.
The snare was pretty fine but the kick was a little too loud compered to the other elements in the track.
The synth/instrument that comes in at 0:30, is way too quiet and has a little too much low-end which makes its sound very muddy.
The piano also sounds muddy, I sugest giving it more high end.
The low pass on the snare and hats at 0:55 sounds a little sudden, maybe something lead into it otherwise it sounds very unexpected.
Best of luck with your future tracks!
