Deathmetal band, what would make this mix more full and in your face?!

I think the mix sounds good as hell. The only way I could think of having a more "in your face" approach to this you could try doing parellel compression on the entire finished track to give it more Umph!!!
 
a tad more high end and a bit less room in the snare should bring everything upfront/more in your face.
 
it's pretty thin in the low-end too. you could add some low end to your kick so u can feel it better. Thread title is a little misleading too. lol
