alright
there are 2 different things you could do that could fix this, both involve duplicating an instrument
either make another copy of your low bass distorted thing, or your synth, and get rid of some of the reverb, and eq it high from 400Hx to about 2300Hz
compress the shit out of it, sidechain it to the rest of your instruments (maybe not the synth strings) and then make it come in at around 18 and fade in, to the point at around :37 where it would play that sweet lead tune you got going on there.
heck, i got time this week, i dont know if you wanna give it up, but I wouldnt mind makin a revamp pof it, asnd send it back to you to submit, just put my name in the comments? eh? eh?
i dont know how good i could do, but i think it wouldbe fun to give a try, since your composition is pretty freakin awesome, just needs mixing
