Check my mix please - Licrest (death/doom)

About to release a new Licrest album, and I want the mix to be as good as I can get it, so I'd appreciate any feedback on this. I'm going for a thick, huge, crushing rhythm sound overall, so the bass is pretty prominent. I'm a bit concerned with the lead guitar tone - I think it works but it may need some tweaks to keep it from being harsh. Also maybe a tad less high end on the death vocals. a flood of anger.mp3

Finding it a bit hard to get into the guitar tone in general. Sounds very boxy and/or phasey.
