Hey Tobias,
some honest takes:
The starting chord for Pieces' bridge/chorus(whatever u call it in this song) is wrong, u might wanna listen to the song again.
Vocals were very avg, to be frank. But I can't sing punk for nuts, so maybe I don't know any better. Just didn't sound too pleasing to my ears, sorry. It's not easy to find a good vocalist anyway yea.
Bass...couldn't really hear the bass guit v well, maybe it's just my speakers, but I felt the bass wasn't there to anchor the rest of the band. The solo duet w the lead guitar at the end of hellsong was rather messy.
Lead guit...the solo-playing was rather lifeless...sounded to me that the main pt was to hit the intended notes. Could take it one notch up by articulating the notes better, using vibrato/slides/bends. Some v off notes in some places.
Have fun jamming together n learning, thanks for sharing ur music. =)
