Nice, nice work.
I would use the word "lush" to describe the instruments in this.... Loved the inversions and bass not playing on the root in a number of places.... bells are perfect.
Really well done. I could see where some soaring, singing , wailing (as you say) guitar could fit into the early parts of the song.... Kinda a Santana Europa sound.... singing sweet smooth gain.... BUT.... what you DID play in there is super tasty, so I wouldn't be sweating over what could have been.
