Turn down the sustain pedal and get rid of the release on your bassline because it's overlapping the notes and also it's quite repetitive and offkey. In order to fit correctly you should find the rootnote by sliding it up or down an octave depending on what synthesizers you have programmed on your song. The drum-kit however is a big mess because it doesn't fit at all, it just repeats every few bars. But you'll get better as time goes by.
