Both sound really scooped and the second has some really weird phasey sounding shit going on.
Go back to the first mix (hope you saved it just incase!) add more mids to the guitar sound, use a decent impulse, and then boost 400hz, cut a bit at 500hz for that scooped percussive thump and tightening the tone up (but not much, -1.5db cut at the most? maybe -2db?) then a boost at 1.5k and maybe somewhere in the 4-6k range too if it needs it? high pass at 90-100hz and low pass at 10k-12k?
Should get you a rather fucking beastly sounding guitar tone.
Drums, the second mix sounds better, more smacky, ala Bulb's old DFH kit, Tesseract (or however you spell it haha) and Meshuggah. Needs more low end in the snare tbh. And bring the kick up, scoop the mids, boost the low end at the point where it has that kick you in the chest feeling and boost it at the point where you can really hear the smack.
