Beautiful guitar work, I particularly like the parts where the two guitars play harmonies together.
The song is quite relaxing and well produced with y good choice of instruments.
As far as the vocals are concerned, the voice you have chosen suits the song very well, but the prosody leaves a little to be desired.
Since I am not a native speaker either, I know this problem all too well.
There are several free text-to-speech tools (online, and I believe Windows even has one) that can read aloud any lyrics you feed them, giving you a better idea of how a word or entire sentence flows.
Apart from that, I really enjoyed your song [Linked Image - Only viewable when logged in]
