Hi,
Nice to meet another ambient fan 
. You’re probably familiar with the ambient music of Hammock , your guitar sound reminds me of this. Like the sound and mix very much. You might try and go a little further even in the use of delay’s. Almost drown in it.
The synth bass could sound even more like a drone .
Chihei Hatakeyama / Philip Wilkerson are very inspirational in this area.
Good mix.
well done
Peter
