Photo Analysis: Coming Through

What works well:

The composition is pretty solid. Everything sort of funnels you straight toward the train → the walls, the balconies, the hanging tarps, and especially the curve of the tracks with the slight shimmer.
The thick, cluttered environment creates great layers depth and visual interest. Even though the space is tiny in itself, it still feels rich in therms of exploration possibilities.
The little group of people on the left adds a nice sense of scale and everyday life. They make the train look even bigger and more intimidating.
The whole scene has a natural tunnel effect, the buildings squeeze your view to the middle, and the tracks are the icing on the cake.

What could be better:

Getting down lower could have been another option. A lower POV would have made the rails feel bigger and more dramatic, and the tracks would have pulled your eye even more forcefully in (but that is just a suggestion).
The composition leans slightly left-heavy with the people, lighter wall sections, and visible details all sitting on that side.
The right side disappears into shadow, so it becomes the “weak” side even though it probably has interesting details we can’t really see.
The train sits a little low in the frame. Bringing it up slightly could have added a bit more balance (another point that speaks for getting a bit lower).

What works well:

The light is moody and fits the setting overall. It is soft, nothing harsh, and it wraps itself nicely around the alley.
The train headlights are a strong element, they immediately pull you in and make the train the star of the show.
The faint shimmer on the rails is great. It catches just the right amount of light, exaggerating the leading-line effect and again guiding your eye straight to the train.
The atmosphere is, as noted, rich —> all the clutter, the plants, the tarps, the cables everywhere. It feels raw and interesting to see.
