Honestly, I see some good stuff, but I think you "just missed" on quite a few of them.
1. This is fine. nothing really to complain about.
Glad you weren't ale to find anything to complain about.
2. Cute idea, nice scene, but I feel like we're too close to them or something... I know what they're doing, but I feel like I lose some of the context somehow. Also his hands are kinda close to her face and the oars are kinda dominating.
To get farther away, I would have needed to stand in a flower garden... Not sure how the management would feel about that. 
But I see what you're saying.
3. Fine, but watch the framing. With dance shots you really want to get their heads up to the top of the frame and cut out any unecessary background stuff.
This is a brother-sister hug, not a dance shot.
4. Someone else pointed out the floating bench thing- honestly I would have missed it, but good point.
I agree, it is a good point. The bench is actually hanging from chains anyway, so technically it is "floating" in some respects.
5. The crop for me in this one was a little weird... or the framing. The space behind her head is fine, the space behind his head feels chopped. It literally feels like you twitched a bit when you took the shot.
I cropped this in on the right side, I'll post it below. I think it works better when it's more centered.
6. The people in the shot might have been fine, but that overhead thing is a major distraction and ruins the shot utterly, IMO.
To each their own. Some like it, some don't. I appreciate the thought. It's an umbrella from, as it was a rainy day. I personally think it adds context to the photo, but I can see how it would draw a lot of attention.
7. The framing feels a little awkward, which you could fix with a crop, but those ferns up front are really intrusive. A crop may fix them as well, though. I'd say play with it.
I recropped this as well. Got quite a bit tighter with it.
8. This one is very cute. The background is a little distracting (there's a LOT going on... some lady peeking through the trees there, etc.), but I think it works ok and probably reminds them of the scene. IMO this is probably the best shot of the bunch.
I agree, the background is a bit busy. Lots going on in the childrens garden. Haha.
9. Cute. Nice moment. I think if you cropped in a bit on the right and maybe a hair on the top it would really pull it together.
I'll work with different crops tonight. See what works and what doesn't. I do know that I like it the way it is right now. Fits very well with RoT.
10. Ok, I guess. Crop a bit.
Crop/framing was intentional.
11. Ok, I guess.
12. Nice moment, but so much of both of their faces are concealed that it feels like it doesn't quite work for me.
Only angle I could get without being in my Girlfriend's shot of the moment, or in someone's lap in the audience. I would have liked to be farther to the right, Ideally.
Really, overall... I think you handle the camera well technically... I think you have some framing and composition quirks. They totally feel like they're just off a LITTLE, though.
These, of course, are just my opinions. Offer void in Alaska.
