It doesn't work AT ALL in the thumbnail, but I find it very arresting seen larger. I don't know how big it needs to be, it's possible it would stop being good if it was too big.
Basically, I like all of it. Paths, roads, train tracks are always powerful beyond what we expect, and this has a lot of echoed lines and textures to make it graphically interesting. The one quibble I have is the texture of the pebbles (?) in the large area between the tracks and the fence. These seem to be rendered in Black and White, without greys. Not sure if that's deliberate? It makes it very busy and hard to look at, for me at any rate.
