Sounds good man, this is a neat riff and I look forward to hearing more stuff from you! That said, you have asked for critique, so I'll try to be a restrained dick about your mixing.
Take that silly master limiter OFF, that's a good start. Different tracks have different needs, so trying to do it all at once with one big compressor isn't really helping anything. You should (IMHO) be mixing with a dry master channel anyway.
All I'm hearing is the lead guitar, snare drum, and a bit of cymbals. If you want your percussion to shine through without losing headroom try giving them a sharper attack - you could use a transient shaper plugin, or just a compressor with a slowish (~150ms) attack to give a bit of a click. Remember to turn off the makeup gain, you're sharpening the transient not bringing out the details.
Should you choose to adopt that strategy, keep in mind that you need one of those transient shapers/compressors for every drum slot unless you're VERY careful / lucky with your compressor settings. I would use one on the kick, one on the snare, and use a very light bus compressor on the whole drum kit to bring out everything else. Careful with the cymbals, sometimes I like to put them on an entirely different track since they don't really behave like drums.
The bass sounds like an absolute mess. This can be good or bad, depending on what you're going for, but I just hear a muddy blur of noise. If you're using your bass for texture, rather than rhythm, that might be perfect - if you want individual notes to shine out, though, or the bass to have any punch at all you're going to have to clean it up. Highpass that guitar, for one, and think about why you doubled your bass. Did you want more dark ambience? Good, carry on. Did you want the bass to punch you in the chest? Well, it's not always about going deeper, it's about the right transients at the right frequency. I'll point you back to the highpass filter and compressor/transient shaper for that.
Disclaimer - I know nothing of metal music at all and I'm just a bedroom musician, so take what I say with several grains of salt. I can barely play guitar and I haven't touched a drum set since high school. Also, my genres of choice are mainly electronic, so I'm usually trying for a VERY different sound than you are and all my advice might be pointless.
