This was fun! I personally felt like the percussion was a little too forward for my taste, but otherwise the mix was great and your instrument/soundfont choices were nice!

I think this is actually a good point on this one.
The percussion is something I would EQ down a bit for this. It's less that it's forward and more that it just shoots all these high pitched tinny overtones into the rest of the track, rather than laying the foundation.
An interesting related point is that guitars with different types of woods and overtone profiles tend to be recommended for different styles of playing. I can't remember which woods did it, but some woods are really in the middle of the overtone profile, while others are "scooped" where there is a lot of bass and treble, but less mids, so that there is less interference with the vocalist.
Overall though they did well on this submission. It raises the point about overtone profiles in general and why instruments are layered where they are.
