please check my mix(doom/death)-POD XT with DFHS

Good stuff...
I didn't like the drums too much, not enough punch...
The guitars in the beginning sound abit muddy but when the lead comes in it fills nicely.
What guitar and pickups did you use?
what amp model?
 
Change the snare. You can get a tighter and crisper sample and then add some air or a bright reflection 'verb to go for the sound you're after. Maybe even use more top mic.

Lower the volume on the rhythm guitars just a tad when the riff comes in. That'll help make it stand out - as it should, it's a great riff and sounds amazing when it's got the right context.

Not a half bad mix overall though. Like I said I really like that riff that comes in!
