Ohhhh these are all so so good <3<3

The first one, am i right that she is working in the bowels of a train, (the motion and the smoke) but you just capture this snapshot so well, so immersive in her climbing up the rungs of the ladder, not sure the wider context actually matters.

undying wall of smoke

such a beautiful way of describing it, the way it pours out, how it plumes and drifts, a wonderful example of your strong descriptions. You root the story and imagery so well in the prompt artwork, you really bring the picture to life here, which of course has to be the goal of this contest.

Something about it has the feel of coming up for air from a busy, hot engine room (or something similar)

front-row seats almost

This, showing the contrast of situation and status, the closest someone from the bowels gets to a first class view.

Some wonderful use of language

the rags of her body

i can just picture her limp limbed, the flop of thrown rags, the wear of a long day, so much conveyed in so few words. Then the sun kissing her face at the end, oh its just so pretty.

and that line, just got this song in my head now, which i love, so not complaining ;)

And outta break, have to try and return for comments on the other two here <3
