hmmmmmm

Overall, good matching of the origional sound, but this isnt much of a remix, just a synth test, honestly.

Want the song to be as best as it can be?

Start all over again.
Listen to the real song.
Get the bassline sorted.
Remove the piano.
Listen to the structure.
Fix your drums.
Remove the other synths that don't fit.
Work on your mixing.
Follow the pattern of the song.
Stick to the actual melody.
