Amazing. epic song.
I was wondering how to make those synth plucks you use around 1:30.
what you have there is excellent however, I agree that is it incomplete, I'd say what you have there is basically the intro to a 7-10 minute long song. my suggestion on how to continue it would be to have a vocal track start around 3:15 and continue to around 4:20 during which time you would cover verses 1-2. there would then be a drop followed by a the chorus, verse 3, chorus, verse 4 chorus then repeat 1:24-3:16 then have basically the first 30 seconds of this but reversed as a conclusion.
just my 2 cents if you ever want to try to finish it.
