Straighten up ALL your verticals!
Sorry I would have never thought this was in a mansion if you haven't mentioned it. You should have taken pictures outdoor with the entire mansion in the background to show where you took the image. I am sure there are lots of nice rooms in there with 4 post beds and such, if so you should have taken pictures there also. Tight crop doesn't work always IMO. #7 is just a NO.
Sorry for being harsh and a dick but that's the way I learned to be better, by letting others tell me what I did wrong. I realized, practiced, learned. I hope you don't take it offensively.
#5 & 8 are screaming for black and white. Sometimes the blown out sky behind the trees still work on color photo, but these 2 I think need to be black and white. I also wish the bride have different expression everytime she smiles. She looks the same on all of them. I wish she closed her lips once in a while too and just smile a bit. I think you did pretty good.
I actually like the last pic you posted if you had more room to the left (i like giving more room to the left than right because she is looking to the left). I think she looks fine. She may need to smile just a tad. My preference is, if you want to blow the back ground either dont do it and use flash, or just make it completely blown. Nothing in the middle. For example I like #6 because it is completely blown. It is an awesome shot I think (kinda dig the texturing too). #5 and 8 I feel that you should have blown the background even more until it is completely white, or you should have exposed it down more and use off camera flash. Does that make sense? Thats why I think they look better in black and white.
