Jesu, Joy of Man's Desiring (Arranged by Myke Didgett

After listening to many recordings of Jesu, Joy of Man's Desiring by J.S. Bach, I decided to have a go at arranging my own version of it. I did not look at any score before, during or after writing this, but I did try to purposefully differ some notes and chords to make it my own. However, I strived to keep Bach's trademark 'freedom' in the voices of his music. Let me know anything, including how I could improve this score!
