Its ok, but you really shouldn't stick with just yourself. Make yourself good at one thing, not everything. It will take away from the quality of the music you want to make. And there is more to death metal then just evil words. But hey thats you perogative not mine. But seriously you should join a band. And you might want to think about matching the tunes better and mastering the harmony of them. Its really really simple the tune you did, but i realize that its hard to do anything really complex when your a one man group. But seriously m8, work on that growl of yours, its to low to be understandable, which it has to be to a certain point imo. Your making a good start but don't stop there.
