Magnificent.
You did a fantastic job capturing the mood here, both in term of arrangement and mix. The loose timing on the guitars gives this piece a great laid back feel, and the low mids really bring out the warm nature.
I'm a big fan of ambience use properly, so bonus points to you for going out and actually recording some of your own.
If I had to be nit-picky I would just suggest making sure to draw the line between a stylistic decision and a mix technicality. The warm frequencies add a lot in this case, but take care that no range overpowers the other by too much.
All around, great work on this one.
