Considering some of the bands out there , if this black Metal Feel is all you'll be doing you'll probably be fine but if you want to stretch into other Genre's of Hardcore you'll want to improve your' range.
Also this goes to both you and to Daniel Towsley, If the purpose of uploading these is to show how well you Growl, Don't add filters/Fx [especially not reverb] , however, I do understand that as a song you're heavily inclined to.
Thats my criticism, hope it was constructive.
On a few lighter notes.
A) This is my First Post!!!
B) Glad to see other Screamers On Here. Was worried I'd be alone XD
C) Your' Band Sounds AWESOME! Like proper professional about to get signed awesome !!! ;D
