I have made a bit of a sorta speed metal intro into a song, but no song yet?
I was wondering what chord progressions, key changing time changing or whatever the hell you guys think would make this a brutal speed metal song (doesnt necesarily have to be brutal, but speedy somewhat )

Heres the GP4:

if ya need a .txt version lemme know i'll post one.

Cheers and thanks for any help anyone!
Powertab or text please, because I would like to help.
