Please give me feedback on this drum and bass mix(drums and bass guitar)

[keenly]

I am mixing a death metal track from scratch, all raw multis. I have decided to do drums first, mixing each track in Mixcraft Pro 7.

Here is full drum kit mixed in surround with bass guitar.

Please crank and give some feedback, cheers.
