A very sad drawing, but a very excellent one as well.
I read the short fan fic and your drawing fits the mood of the story very snugly. Im a big fan of shadeing, and without this effect this drawing would fall apart. An excelent job indeed.
The glowyness(?) Of the drawing also brings out another effect, hope and the feeling of hopelessness at the exact same time. It's hard to think about that, but the Orange glow of the lantern really makes you feel warm and fuzzy on the inside, but it also makes you feel as if the only hope is fading away into nothingness.
Her facial expression also brings out the feeling of hopelessness, as she is not squinting while crying, but open eyed, as if she is accepting her fate, but its tearing away at her from the inside.
Very, very good job.

I reckon the saddest chapter is the one about how "every pony is made for love" or something like that. That as just sad. And depressing, almost inciting suicidal feelings. That author really messes with ones emotions, and I think you have captured that.
