Hey, the first thing I noticed I liked in this was the continuous use of nature as a theme. Several parts use strong imagery and seem to try and develop a bit. Particularly in the bridge/chorus parts. And the use of that theme is consistent throughout so it retains a uniform feeling. I like that. The beat/rhythm of the first two lines of the verses could be quite interesting to hear depending on the music as well.
"and you leave me,,,like a bird, in a tree
singing,
singing."
I like this image, although maybe an adjective for singing would evoke more meaning? Sweetly, softly or simply for example? All I can think of are "S" words because the repetition would sound good there but maybe that would work?
"wishing that your kiss
that's left me in this mist
never clears."
Two things about this part. It feels awkward to me, maybe it's the use of 'th" sounding too harsh, or maybe the double use of "that"? I don't know. Also, do you wish the kiss never clears or the mist? "Never clears" appears to be referencing the kiss not the mist, as in "Wishing that your kiss, that's left me in this mist, never clears". But one usually doesn't clear a kiss right? Saying "Wishing for your kiss, that leaves me in a mist that never clears" or "Wishing that your kiss will leave me in a mist that never clears" might highlight what I mean?
"like echoes out of seashells"
This is my favorite line. It really stands out to me and I agree using something in it as the title would be a wise choice.
A good draft though, with some editing and some thought it could be a very compelling. For instance, the song opens implying there is a relationship but in other places it evokes a certain distance or separation, as if there is only a yearning. But what do I really know anyways. Good job, I enjoyed reading it and did so several times. (:
