Listened to the most recent mix. The guitars sound digital, and not in a good way (I'm actually a supporter of amp sims when dialed in properly). Drums are way too buried, and like mjbphotos mentioned, there's no bass to be found. As I've said in the MP3 Clinic a million times, PLEASE GIVE ME SOME BASS!!! The bass sounds like it was high pass filtered from 200hz and down. I'm sure it wasn't, but it may as well have been.
Until the levels are all balanced and vocals are recorded it's really hard to get a good critique here.
