I would think this shot is more architectural than abstract.
As for whats abstract and whats not, i don't think (at least not for me) there is a definitive idea of abstract (since that would actually be an oxymoron in itself) but then again, it's quite subjective.
It's doesn't matter whether it's abstract or architectural or etc.... But its just beautiful. The lighting was wll balance and the pattern is just great. I would prefer to have crop off the roof and the ground. Just my 2 cents worth of though.
