I enjoyed the relaxing ambiance of this song, before to start writing the review, I sat down comfortably on my seat and listened to the whole song. I was totally caught by the song and thought about a girl sat down in the fields seeing the seasons changing, it really stimulated my imagination - sorry if it sounds stupid ;).
On the music now, the chord progression - from 1:06 to the end - was simple but effective as you said. The chords you chose were nice - not the average beginner's chords - even if they weren't too complicated, that's a nice compromise. Also the arpeggios in the beginning were cool and well played.
The other thing I enjoyed was the way you panned the two guitar tracks giving the whole thing a nice stereo rendition result. And since you played it with no metronome, it was a bit out of synchronisation conferring the song an authentic sound to it. The overall "rough" sound emphasised that sound as well.
Once again, you proved you can be a kick ass acoustic guitar played/composer as well as one of the most kick ass rhythm guitarist I ever known. You get my ten and five without a doubt.
