Awesome, dude. Sounds good to me but because I'm a guitar dork I'll comment on those.
The rhythm guits have a touch of the squishy squashy sound (not much but I noticed it) and they sound a little more "small room" than the vocals (which sound great BTW).
To try to get rid of the squishy squashies I'd try an extremely narrow notch filter to sweep until I found it and bring it down. Maybe not a full cut though.
To get rid of the "small room" sound I'd try cloning the guit tracks (if you haven't already if you have just use the clones) then nudging them ever so slightly to cause some delay OR send them to a delay bus. I just think they sound like they are in a different room than the singer and the drums. If you used a delay/reverb bus on the vocals try inserting sends that route to that and blending them in just a little.
The lead guit sounds great but it's not cutting quite as well as the rhythms so I'd try a boost sweep in the high-mid range to find the "bite" just to give it a bit more cut to match it with the rhythm guits a bit better and maybe a slight high shelf for some sparkle.
The bass seems a little buried but that might be my speakers as well. Still though if you can clone the DI track and give it a low shelf boost so it's flat but bottomy then blend it in it would really round out that bass part.
After all that I'd maybe try an IR reverb bus for everything to give it an overall live sound like you were watching them play it in a small club. This is screaming for a live sound. This might put some of the reverb/delay that's already in the track over the top though so just blend very carefully or adjust the delay/reverb that's already on the track.
As you know I am not a pro but you seem to have fun with this stuff and this is a great track so I figured I'd toss out some things to try.
Seriously man this sounds awesome. Just needs a bit of glue and space to my ears. Speaking of glue if you have the PC2A that might be a nice comp to throw in on the Master and maybe the Console Emu to push it into a nice warm vintage metal vibe.
Seriously this got me excited. I'll shut up now. Good job. ;-)
