Thank you again!
Yeah the tyger was an interesting piece for me, because I originally wanted to doit in a different perspective. And I know what you mean, the landscape where I live also saw its industrial phase in the 20th century, its over since 1989, resulting in ruinous factory buildings all over the place... somehow quite a charming atmosphere indeed!
My idea was not showing a factory in its similarities with medieval cathedrals, but as referring to a poem by William Blake, which you might know anyways
But you're right, there are parallels between the religious buildings and the industrial ones, and I've heard people calling specific industrial buildings "concrete cathedrals", or similar names. And it somehow makes me think about the parallels and differences these two types of buildings represent, when speaking about values and virtues in society and so forth. A factory might in this sense be a cathedral for the modern values, if you want so.
