Happy new year, Robert

As Charlie said, I'd also not heard of John Martyn before and I also shot over to Youtube to give your reference song a listen. Both songs are interesting and unusual. I preferred your song over his.
And I agree with you.
It is a very good exercise to follow the styles of favorite musicians.
Sometimes I also borrow the chord progressions of my favorite songs.
Enjoyed my listen a lot.

Best regards.
