Black metal mix

Well, ur mix totally is black metal hahaha
No rules in black metal mixing mate. Tbh it's very smooth and clean,

Sounds a bit dull to me. unless that is what you were going for i'd try brightening it up a bit especially the guitars but I don't know what you were referencing. Some long reverb on the kick and snare would be cool for a mix like this.

drums sound too dry and your guitar has too much gain to distort it
