Metal Guitar (Random Riffs)

Here&some random riffs I&thrown together over the past couple months. This is not a song, just a random compilation of riffs I&created. It&highly influenced by Lamb of God and As I Lay Dying. I am not intending to make my riffs sound like any other band out there, just playing what sounds good to the ear. :) Comments on what you think would be greatly appreciated! :)
