This is a really nice photograph. There are so many things I love about this photo! Allow me to elaborate on that.
The first thing that struck me, as it would to any viewer, is the grandness of the bridge which is in a deep ravine. Not only that, but the fact that the viewer is able to see the back of the train adds to the feeling. Another point to be noted is that due to the photographer leaning on the window sill, it creates a temporary effect of the whole train tilting. The man in the photo makes for an interesting addition to the photo.
One thing though I would like to point out is that the photo is a bit too light. Without a certain richness of colours, it makes the whole photo a little less appealing.
Overall, nice work.
