Okay I see what you're doing now, thanks.
If you're just starting out, go for it. Throw some guitars and bass in, vocals, maybe play with samples, effects, EQ etc and try to get something you think sounds cool. You'll learn from that process even if the immediate result isn't that impressive.
I think the drum tracks are usable, but they're a bit tame in my humble opinion. Brutal death metal drums are usually spastic, lots of tempo changes, crazy fills, blasts, etc. Death metal is also more likely to be closer to "through-composed" like classical music is. Basically, rather than following a predetermined and cyclical verse-chorus-verse structure like a lot of pop and mainstream rock (or even trad metal, death metal composition tends to kind of slither around, changing as needed throughout the song, which creates the effect of being on a journey. You can see that if you listen to old Morbid Angel, Suffocation, Cryptopsy etc. Basically, I would change up the patterns a bit more, try to avoid repeating and dragging out singular patterns for too long. It's okay to do it a little, but just keep it varied so it'll be interesting. Fills work wonders.
I'm not sure how you made these, but they sound like they could be drum machine and at first, I thought that they were AI which is why I reacted the way I did initially. If you're using samples or drumsynth, maybe more natural samples would help. You could also tinker with EQ and effects, which applies to drum machine and real drums.
Most of the stuff we as metal musicians try to emulate is older and was recorded on analog equipment. Trying to make your production sound "good" in the modern digital era context is a futile endeavor because it will never be super high-fidelity. If you chase modern production standards like those that you see in deathcore and stuff like that, you'll end up with a decent sounding recording that has no punch and sounds very unnatural, and it still won't sound as "clear" as something like Whitechapel. Just work with what you have equipment-wise and try to make it sound real. There may be some emulators you can download to help you get a more classic sound, and there are also effects you can use like panning (left/right speaker balance) distortion, delay, echo etc.
I'd listen to some isolated drum tracks of bands you like.
