You might try this in portrait format, cropping out the sides to emphasise the tunnel and
its leading lines.
Either a point of interest at the far end of the tunnel — or nothing, if your intent is to say that
there ain’t nothing at the end of the tunnel/journey
Agree with the crop suggestion, but I love the “spidery” feel to the tunnel,
it is a definite tunnel but light and airey, a little over saturated maybe, but
a nice shot all the same.
