Modern metal sounds abound.
As a matter of taste I think the guitars are a little too fizzy. If they've been run through sims that would be the most likely cause.
I think the kit sounds pretty good though the kick drum isn't EQ genre specifically - the flicked aluminium Milo foil thing. I MUCH prefer a kick with more thud & thwack and less click as you've done it.
If you're into arranging then you probably do have an inherent sense about EQ as that's, largely, what arrangement is about - fitting the sounds together. You just need tools that allow you to work intuitively. Reaper's parametric EQ is cool.
Big niose - well done.
