August Burns Red Full Instrumental Cover

[ChickenStomp]

I'd love some feedback on this rough mix I have. I think I have all the levels pretty close, but something is off about it.
The bass guitar is all midi, so maybe that's it, but I don't really have another option for recording bass guitar.
Any advice would be great, thanks!

I'm not really hearing much bass at all. The drums are too busy and loud for my taste. The rhythm guitars sound a bit fizzy and lacking in body.
