I think the low end is fine. But somehow your mix sounds pretty dry. You could get rid of this by using a global reverb send with a room setting
And on the guitars I'd cut a bit more of 3-4k. Don't like the fizzling sound of the guitars. The bass also sounds a bit boxy. So with a cut at about 400-500Hz the bass would sound heavier I guess .
But don't get me wrong, this is a good mix.
