Test Mix 666

It sounds like you're trying to "yell" those vocals quietly. Try to practice actually yelling them to get more aggression out of it.

The snare and kick could both be a little more punchy. Try a small boost around 250-400hz on the snare. The kick actually sounds like it would be better suited for rock... something lighter. Maybe try a different sample? Oh, also the cymbals are a little too loud.

The guitars are kinda fuzzy.
