Great job for a first solo wedding! Looks like a very cool place to shoot. Here are my thoughts on the photos you posted:
1. So-so bridal portrait. It's nice and sharp and the light is decent, but I would have framed her on either the right or left third, or shot in portrait orientation, and not cropping off as much of the head. The tattooed arm in the background is also somewhat distracting, and her hair becomes lost blending into the dark background.
2. Sweet shot. I'd like to see what it looks like with a little longer shutter speed - although depending on the speed of the carousel and having either IS or a tripod, that may not have been possible without it coming out completely blurry. The fence on the left side is a nitpick, but not a deal breaker for me. Nice shot.
3. Cool building for bridal party shots. I would have posed the couple to the right of the B&G to lean against the opposite pillar to mirror the couples on the other side. And the lonely bridesmaid is a little sad, but hey, that's what happens with uneven bridal parties.
4. Fun shot. What was your shutter speed? If it was possible, I would have bumped it up a little to really freeze everyone's movement (groom's hand/face, for instance). I'd also bring up the shadows a little.
5. A little too centered for my taste, and watch out for chopped off fingers. Otherwise not bad.
6. Nice, they'll like this one. Bring the darks up a bit and clone out the red dot above the groom's head and you'll have a winner.
7. I'd crop out the speaker and a lot of headroom, leaving the couple on the right side of the frame. Looks a little soft too, but a nice moment.
8. Too centered and wide. I'd crop out a lot from the top and left side, leaving the couple framed in the left third.
#3-6 all look a little cool to me, may want to check the WB on them.
Hope this is helpful and not too harsh. Overall I think you did a great job, especially for a first time solo wedding!
