The detail in the lit walls/ceiling is great and we are led nicely up the stairs to the light source. I agree about trying portrait and maybe landscape with the top of the stairs less centred. Am sure this would look much better as a large print where the detail would really show itself in the shadows.
Looking upwards and from dark to light has a certain symbolism, you remind me. Finding those locations that are imbued with mood, such as this one, is a worthy pursuit. I will have to get out and about more.
