A very nice set. #5 is wonderful (I am a sucker for ring shots though). Some of the textures seem a bit strong imho, but I am sure the couple will be happy with these.
All very good shots but, personally 1-4, 13, 15 nope, I know your trying retro and I respect that and other opinions but the PS IMO does nothing but ruin your good work.
But I do wonder how the more processed shots will look when they are less fashionable - and even if the bride and groom will appreciate them now (although if they have seen and expressed a liking for this style which they may well have done that's fine ).
I certainly feel that an album with both styles in might look odd to some.
Yeah these are all awesome. I like your color low contrast look in the beginning. I would like 15 more without the texture. I would process 13 the same way you did 11. Great stuff.
