oh my. I didn't expected to see this when I saw preview... amazing work :)
It took me almost a month, but it was very proud, I studied many references to try to do the best I could, here https://br.pinterest.com/jonatalopes35/arquitetura/
Insanely detailed, indeed. The texturing of wood panels is especially awesome, it's a technique that few people practice and master. If you allow me a critic, the columns are weaker, I think they suffer from using black (or dark grey) for carvings no matter the direction of the light. I think you've learnt and improved since drawing this, as many of your other sceneries don't have this issue, and you do sometimes use lighter outlines when the edge faces the light source.
These are crazy! How long did it take to make all these church details? 
Thanks!
