Very nice!
My only critical thought; your guitar is "walking" on the vocal a little in the verses.
I am listening on my Bose headphones, not exactly "flat", so it may be they're hyping that a bit.
Hendrix liked to "double" the vocal with guitar in his bluesy tunes (think Voodoo Child Slight Return).
All in all well done.
I'll have to take a closer look at NI Horn's Pro, I'm slowly learning how to use keyswitches.
Your mixer is a pretty good pianist.
