I'd say put samples or learn how to use synths the best i can give you right now is a manual to all the things https://manual.audiotool.com/
For the sample part again make sure they actually go together so they all don't sound all jumbled and confused
i'd say the drums do not compliment the song whatsoever and at it doesn't make sense whatsoever you changed the sample making it an awkward release of the instrument and switched it to something more of a related way
(Tough Criticism)
Nice

drums don't go really well w it
