Not bad for this genre of metal. Raw sounds and mixing fit the genre. However, if you're going to record other genres of metal, I'd suggest working on guitars more As for drums, I'd suggest compressors and getting more mics for best result.
I created new song too. This time it's a cover; Burzum's Dunkelheit. I also tried compressors and quad tracking for the first time, and I think my sound improved a lot. Especially snare sound <3
