Portrait of a Lost Poet (edit 2)

[Truerenigma]

hmmm it seems to be becoming more comprehensible now. I think you want a sonnet for this. But you need a metaphor first so, Try opening with the theater line then, following that line of thought, build the metaphor by letting his acts mannerisms, and appearances (remember you said portrait) on stage symbolically echo his private life. It's been done many times, but I think you have the beginnings of a new contrast to that echo in the second part than can make it work.
