Andi,
well done - good story & song.
The lead inserts in the 1st two minutes are a little louder/cut through more than the vocal so you might consider dealing with that.
The vocal is very naked in the 1st minute or so are quite exposed and naked as intended. However your breathing is quite loud in this section and it might be worth reducing those bits with some automation - not eradicate them just reduce them so they sound less harsh.
Andi & Wolfi do great - lots of comparison with early scorpions.


Cheers
