A nice shot, quite dramatic with the smoke coming out of the funnel (if that's what it's called!) contrasting nicely against the sky. You could perhaps bump it up half a stop without losing that impact.

With respect to some of the manipulation, across the house it's slightly patchy in the blur - the right hand side of the house is more blurred than the left hand side.

I'm personally not convinced with the ragged edge effect. I don't think it adds a great deal, and in a sense spoils the crop with the front right bumper thing missing a chunk. You can tell I'm not a train fan I guess!

Nice natural looking pose that the model has with a touch of an enigmatic smile which I like, but her face is lit a bit too harshly for me. What lighting set up did you use? It looks from the shadows like 2 undiffused lights either side and behind of the camera; one diffused side light may have worked better, perhaps with a reflector, and not washed out her face quite so much. Also, a slightly shallower depth of field would have thrown the background foliage further out of focus and helped to concentrate the attention on the model's face.
