I looked at this from out of the box. If you look from end to end DOWN a curved line of architecture it is still straight on one axis. I appreciated this shot as not one of the norm and it got a 9 for ingenuity, composure and a sense of humour/risk from the photog. WD
Is this the BCE Place? Anyway, as the challenge goes I'm afraid you didn't abide 100% on it as there are several non-straight lines there. I think you'll get many DNMCs.
I like the image per se. The focus is sharp. It provides interesting patterns and I like what appear to be some reflections on the glass. I don`t care for the thicker border though - it competes with the thinner white lines of the structure.
