As a fan of metal, I might as well throw my opinion here.
The music is... decent. The vocals are great; they actually remind me of Dark Tranquillity, 'cept a tad deeper, and that's a good thing since I'm comparing you to a melodic death metal band. Drums are okay, but I really think the lead guitarist should pick it up. Listening to some songs, the riffs are good, it gets boring after a while, so it would be nice to hear some guitar licks and solos after a while if you're going to keep up with the metal genre.
I'm not hearing it, so correct me if I'm wrong, but if your guitarist doesn't know the sweeping technique, he definitely should. It's hard, but practice makes perfect... it'll, for sure, spice up your sound. You guys are off to a great start even though you sound pretty average.
