Bass line oke, build up i dont know, after when the build up start the music loses the power, and after the build up the drop become weak, because the lowered volume. And the Yeeh vocal, it is not fitting in the music, beacause is not compressed. I give you a follow, and when i hear some changes in your future work i will review it, and rate it. P. S. Im not a synthwave producer but i think your music is not synthwave, it more like those music what comes from the Spinnin Record with more professional concept.
