I went for more Hard Core, and a bit less Metal sound. In my opinion, HC is one of those genres that can sound full being fully dry (no reverb or delays). I'm mixing on horrible monitors, in my bedroom, but hopefully it's not completely off
I agree that HC can sound full when they feel dry. But you need at least reverb to make the instruments sound like they are all in the same room. You have a decent mix here, but it's sounding more like a demo than a finished music. I hear some high frequencies that are taking to much space from the mix. Try to work with cleaning your mix and using reverb just to glue it all togheter.
