I'm getting married this April at Sweetest Heart of Mary downtown and I'm starting to look around at some good places to take photos in the downtown area. Our reception is out near Selfridge Air Base so we may swing up 94 or go up Jefferson for some Grosse Point photo spots. I'm wondering where you guys think make for some really unique/intriguing photo backdrops. I've got a few in mind thus far, but I'd love input from some of you who know the city very well. My list thus far:

Guardian Building Interior
Michigan Central Station
Whitney Mansion
Brush Park Mansion [[TBD)
Belle Isle Fountain/Downtown backdrop/Belle Isle Boathouse
Dequindre Cut Graffiti
Woodward Ave [[backdrop of Whitney/Broderick Tower)
Riverwalk
Fisher Building Interior


I know some of these are "stock" wedding photo shots that photographers do, but I'm ok with some of them, I just don't wanna overdo it with them. I'm looking for some hidden gems that people will be really impressed with. Any help would be much appreciated. Thank you.
