Personally I'd call it Gone but not Forgotten. And the reason is, firstly your title describes something that may or may not be there. In my opinion and imagination it's a picture of someone loved (by the heart on the pillow) who has now departed. Old people often sit by the window watching the world go by. As well, out the curtain is the great void and beyond. I find my description far more emotional and adds a lot of gravitas to the picture. To me that's what the picture says. Just my interpretation.
What Michael describes is precisely the reason I hate artist statements or too specific titles (which this is not as no such view exists here). When a photograph resonates that strongly with a personal interpretation, nothing should get in the way. Magicians don't tell. This has magic! Don't tell!
Yup, to me this one evokes yet a completely different feeling. I can almost see my granny sitting in there. Endlessly streaming some hand-knitting and peeking out at the world every few minutes. Lovely mood.
