Hey there, thanks for the comment dude! It means a lot to me.
You're right about the "lightweight" vocals, I realized that after a certain time. I think dryness of the mix caused by mastering. I didn't really hard-worked about the mastering, because I'm new about these stuff. So I mastered it again as I learn about something more "advanced", maybe I'll post it here if I find some free time.
By the way, I dunno about the sub-genre thing too. Of course I know there is bunch of sub-genres, and trust me I listened every single sub-genre of metal, but I don't know what exactly my stuff sounds like. Or can't decide it, in other words. Basically I love "melodies", and "death" elements, so I call it melodic death

Anyway, thanks for the input again, I appreciate that!
