i'll be light on you. but this needs a lot of work if you actually want to consider it a song. that kick is no good, the shaker is too thin for the bassy kick and high resonant synth in the background. that random clap sounds hilarious when compared to the crash's delay, because the reverb is completely different.
Do some homework, actually compose a song then change the instruments. also if you wanna keep that high detuned saw, i suggest you layer it with something, its stabbing my ears
