I pretty much agree with what these guys are saying about the bass.
There are things I like about the drums . . . but overall, I'm missing some of the attack. When you compress or limit, you should leave some room for dynamics. I mean if you're just flattening it, there's no room for the initial attack of the stick followed by a slight pumping, then sustain. You just get this blop of a sound. I like to use the term "thwack." There's no "Thwack!" left -- it's just "AAAACK"
I'm probably being too critical with the drums, because they are close, especially for someone who's just starting out, moreless.
Other than that, I like how you've mixed the drums and I like the natural room sound you seem to be getting.
I'm kind of divided on the guitars. I like the arrangements and I like the ideas you had for the tone and what not. But I just think you should start spending more time experimenting with different amp tones, trying to get stuff that just really kind of jumps out of the monitors . . . and when you go for that 2nd or 3rd layer or part, try out a shitload of different kinds of tones to find ones that compliment one another while offering unique tonal variations. Right now it seems like they're almost there, but either fighting one another or just mushing together in a slight mud puddle. I can tell you're headed in the right direction with it, though.
