Maybe I could help , if you still need some
I can play guitar and a spot of keyboard.
So, how many instruments ?? Only Guitar or also some drums or any other stuff ??
Do you have the parts written down in tabulators or in classic notes? I would prefer tabs for the guitar or both (tabs and notes).
Anyway...just go on with composing music parts for wq3.
I think wq3 needs some new parts.
