You're on my page. I've been messing with a progression just like this for a long time so i hope this works out for you.

add more layers to add depth. The following is what I think will open new doors for you in this song

(in drop D)

b (18) 8
g 17 9 7 (5) 4
d 14 7 6 5
a 15 8 7 3
d 0

mess around with those chords and notes to fill in the gaps and i think you'll make progress.
