U used just one synth, i might say to u use more than just one, add some bass or something. Another thing, u could alterate the melody sometimes, turning it into minor scales or something, changing the chords progression, something like that. Just let ur mind fly over, XD.
i like it if you were going for a trap type beat i would add and delete sum things but if its not one its catchy and its gud to vibe wi gud job keep workin hard man
