I really like the material and the whole bit baroqueish vibe at times!
Just felt like that you could've had a bit more instruments at parts, maybe just doubling some stuff to help make the track feel more full, since at times it felt a bit hollow because of that to me.
Other thing that came to mind while listening was that you could maybe try adding a counterline to the melody when the organ solo comes again at 1:00, or maybe just add a second harmonized line under it on the second half of the part, that could , maybe help give more energy/momentum to it.
Just some things that came to mind while listening 😁.
Good stuff!
