overall good mixing, i would master it a bit loader, on my speakers I had to bring volume up a little bit to hear all the details of the mix. Basically the balance is totally fine in my opinion and for this kind of music. The only small detail - bring bass slightly up , give it some character. Maybe parallel compression with some overdrive on it, you know, add some mids without making it like a bass from Slayer album, cause in my opinion bass is a bit lost in the mix.
Post the full album whenever it's ready.
