Maybe Hugo is right... But maybe!!! In your version I like the sense of perspective that enhances the deepness of the photo... Those small white spots in the upper part play that role of giving perspective...
Hi Verena, Again an amaising shot. I think your work is very consistent, and always surprising. Maybe you could have stressed the vertical lines by narrowing the composition a bit; cropping off the white spots both on the left and right on top. (see attached file, only a minor change, though) The reflection on the metal is a bit burned, but I like the high contrast of the print. Excellent depth of field, well done! You never cease to surprise me....:)
