I like the change-up break in Corpse.
I'm not a big metal fan but, I thought the music was tight, the drums was excellent.
The singer can really "actually sing", nice voice, when singing.
Great and intricate bass playing. The guitar is good, but does not take things to another level. Good basic guitar, rhythm parts, but lack few surprises or really breaking out and taking things to the next level. Rising War & Waiting For Silence samples sounded better from the small clip provided, guitar wise. It's hard to really give a good musical critique from short 30 second samples, so I can only really judge the song Corpse.
Overall, Everything stays at one pummeling tone/pace. I would mix things up a bit more as others suggested. Obviously you are all very good musicians, thats not a problem. A bit more creativity or uniqueness in either your song structures or sound would be a plus, to me.
I feel you need something to make you stand out from other bands in the genre.
again I am not a metal head so take my thoughts with a grain of salt, but you asked.
