it seems like the timing/rhythm is off, and theres not really a transition into that new melody at 20sec. also, i suggest using more instruments and to vary your melodies more. and also, use the sidechain on the compressor, as that used in basically all phonk music.
Alright at the start, yanno how you just have the vocals?
Now, most brazilian phonk songs usually just do that.
I suggest adding bass and then after you do that, right click the synthesizer on your timeline, and then go to filter, then click velocity. After this, use the draw tool and underline your bass beat. Double click the green beat, and make the bass start silent and start rising as the vocals rise to start the chaos.
