This is a really good mix, dude... many of the challenges are very well tended to. Just a few things I think could be a little better... The acoustic guitars sound very good in their own right, but if you're going to hard pan them in opposition, you really ought to high shelf cut the treble... the sparkle on the sides channel sounds really good at first but it ultimately gets distracting and a little wearying... I'd suggest a compromise... narrow the spread maybe 20 percent and you can get away with a slightly less aggressive high cut.
The electric guitars have lots of lovely warm midrange content... but carving some of that way and bringing the level up to match would give it a little more definition/clarity, which'd be great during the solo in the intro. During the nylon's dominance they sound great, and the nylon sounds nice too.
I think as a whole you'd benefit from more ambiance... the arrangement is quite sparse so you can get away with more clearly audible reverb.
And the automation is well judged for sure, but the implementation is pretty sloppy in a few places... there are a few spots where the EQ, volume, and panning changes are quite noticeable, so ease up on the transitions or mask them with something else and you're golden. I didn't notice any obvious automation of the FX levels, so great job on that.
Overall... great mix. Better than mine and most of the others so far, just a few technical fixes are necessary (listen to it in phones and you'll really get what I mean about the sides being too bright, and purely subjectively, a sparse mix sounds naked to me without a nice, diffuse reverb or a pad to fill it out
I'm grateful for comments and suggestions. Thank you for listening!
