That’s a good mix, Mariano. Everything is balanced pretty well. Nothing stands out that really needs “fixing” at all. I would suggest making a copy of this mix and see if there are instruments that you can use to spread the mix to make it much wider overall. It feels a bit “down the middle” to me, and maybe that is what you wanted. Personally, I tend to make my mixes as wide as I can, and let the vocal settle down into the mix, rather than sitting on top of the mix. Just a thought in case you are interested in exploring an alternate version. Nicely done!
