You gotta work on a lot of things...Timing is important...You were off time a lot on both songs.
Your overall vocals are okay, but you look like you're straining a lot with your highs (I can tell by the faces you were making during "Hey John" LOL) The highs should flow naturally and not cause you to strain and tighten up your throat
Also you should work on your recording quality...I have some tutorials on my youtube for vocals and recording them:

Having a good quality recording is more important than showing you standing there with your hand in front of your face while your friend says "HAR HAR, FAIL" in the background.
And before you post too much, don't expect any respect from the people here at bandmix. They don't understand metal vocals and don't respect them. And I don't blame them, because over 95% of "screamers" on youtube are these kids that are just TERRIBLE. And they give us a bad name.
The bandmixers need to understand that there ARE professional metal vocalists. There are even teachers that give lessons on how to "Scream" the right way, and how to protect your voice.
I work very hard to develop my technique, attract fans, get subscribers, and stand out over all the garbage on youtube. I have fans all over the internet that know my name, but then I come to Bandmix, and some 50 year old keyboardist that plays "Sweet Home Alabama" every night at a bar replies with a "Death Metal takes no talent, and you will never go anywhere in life" rant.
But feel free to talk to me...I'd be happy to help you with recording and perfecting your vocals
