Ah that good good viking language -- took me back to Age of Empires, age of kings xD
It sounds like everything rhymes, so, not knowing the language, I can't comment on that
I will say I can hear the room noise on your mix can it sounds relatively centered. Could use some improvement on vocal mix which can be learned with online tutorials. Language sounds like sweet silk to me though.
The sax part is a plus
Sub is way up in this mix, as is the hi-hat -- take that hihat down please if you get the chance later! Clap could come up. I also struggle to hear walking bass part over the piano parts. Reverb also sounds overdone on your keys. It sounds cool as an effect on your vocals though.
Not bad! Keep it up!
