I recommend you not to use FL stock samples, they are overused and pretty bad quality. Also there wayyyyy too much reverb on most of the track, be careful with this effect. The guitar introduced at 0:48 plays wrong notes. The bass on the drop is too loud and has a weird ducking effect which could be improved. Also you track lacks of sub frequencies, like on the kick.
Wish you the best for the future :) keep on producing,
