Bass Thumper,
It's quite a courageous choice to stick through the whole with only two chords, D and Gm.
I listened to it until the end without getting tired of it.
There are clever tricks here and there to keep the audience from getting bored.
Enjoyed my listen a lot.
Best regards.

Hey Shigeki, many thanks for the listen and comments.
I'm relatively new to music and until 10 minutes ago I didn't know the chords I played on the keyboard (Nylon Guitar). I just hunted and pecked until something sounded good to me. You can hear this most clearly in the intro after the flute.
Here is what I played. I looked up the chords from here

D F# A - Dmaj
D G A - Dsus4
D A A# - A#maj7
Thanks for triggering me to look these up.
