Hey Bjorn, welcome!
Which song do you want reviewed?
I'll go ahead and review the Johnny Cash.
- Pretty voice.
- Where are you from? Your singing voice suggests that you may have some foreign accent which is "here nor there" , but was just curious.
- Your intonation is pretty good.
- Nice mix/production.
Overall I think it sounds nice. I don't have a lot of critique advise for this. Your voice sounds pleasant, intonation is pretty solid, the color of your voice is interesting, and effective.
Nice job!
