Certainly not polished
Well, it's certainly very first or second try. I recommend using something other than 808 sounds, or FL template sounds.
Stretch out on google and look up some free samples. This track could stay exactly as it is but still benefit greatly from using more solid samples.
Or, if you were to stay with these samples, experiment with effects and mastering to make it sound a little less clunky and a little more polished and original.
Thanks for your advice! I will try next time to put more effort into the song and try to make my next track more refined.
