What do you guys think about my Death Metal vocals?

Ok depth and tone but sounds like you're just talking needs more power and less phlegm
 
It sounds like you couldn't do this with any power, you'd probably cup your hands over the mic to make up for it and within 5 years your chords will be destroyed.

Basically you're doing a vocal gimmick into your mic because you don't have any real technique. You should try to take lessons or watch some professional 'how to' videos.
 
Just get out there and scream/growl like a dickhead into a shitty PA at band rehearsals until you've either sorted it out or worked out that you suck. The internet cannot tell you everything.
