Impossible angel

@artjewl - thanks for your crit. Some fantastic points there, told crisply. I probably won't act on them immediately, but save them for a later revision.
@nikkisto - I type on my mobile all the time, so I completely understand. The 'and you' in the line above changes the emphasis slightly for me, but it's a valid suggestion and thanks for that.
@Igor - I don't quite agree with your suggestions, as they change the intended sonics and rhythm of the poem, but thanks for taking the time to read and comment.
