Really good playing, man!
It's very good but I'd tighten up the low end on the rhythm track, it's taking away from the tightness of the chugs. Maybe just a touch of a HPF, you'll be surprised how much of a difference it makes.
Automate them, maybe, so that when the new guitars come in that they're given room to breathe, this can mean EQ'ing some guitars to that they're only using the range they need. So when a slightly higher part comes in you tuck away those frequencies on one guitar so the other can use them properly. Sort of like the way you can take up an entire 4 seater couch by yourself but you can fit alot more people if you just designate yourself a specific seat :D
Other than that, very good. Quite tight, good muting, some cool layering and harmony ideas going on.
