Dan,

Another strong write.
The nylon loop works well.
Good arrangement, nice build.

For me (an important qualifier, of course), the mix is too Mid-heavy.
Everything seems to be in the middle of the EQ band - and mixed together, they get somewhat muddy.
Actually, "muddy" isn't the right word - so let's go with "heavy" (or "dark"?)
The combination of the vocal (nice!), nylon guitar and bass - they all seem to be fighting for the same space.
When the strings come in, they, too, seem heavy in the mid-range. (the strummed acoustic, also).
Maybe give the strings and that strummed acoustic a good deal of high EQ (drop out the bottom?)
...and maybe beef up the low end of the bass.
The vocal COULD have a bit more high-end (but that would depend on what other changes do...)
Stretch those frequencies out a bit to open it up.
Just suggestions, of course. And the next guy might tell you I'm full of it...
