You've got the scream, I like it allot. 1 thing to work on though is the pronunciation of the lyrics, try practicing screaming a certain word and form different shapes with your mouth until the clarity of the word appears more and keep doing it until you remember with out having to think about it :D

Other than that excellent job on them vocals. :)
