your kick needs to be mastered throw it through a compressor(multiband compressor mess with some settings if fl studio), your high hat @ :17 needs to be a lil reverbed and delayed for a more proffesional filled out sound same with the 16th note high hat. the snare too could use a smidge of delay/reverb. the sounds are a lil dry. we talked about at work. everything needs a lil reverb cuz you like using these sounds in a program but in real life there is reverb everwhere. i like the progression very chill and simple. id just say the percussion needs some tweeking to fill out some space with the reverb. id throw a really reverbed crash at 1:01 to kinda give the mellow part a stronger fill. @2:17 the synth kind of comes out of nowhere so could use a lil better build up and personally i found it annoying. to high and the melody/flow needs a lil work. all in all this track is solid just could use some tweaks to sound cooler
