Looks like a nice couple and these are certainly decent shots. I assume they liked the photos and this is just a learning exercise. So, skipping the platitudes, here are my suggestions (all just my opinion of course):
Shot 1: Crop tighter to bouquet with current image. For future, if this is bouquet shot and not bride shot, be sure you have enough DOF to capture all the flowers in focus. If a bride shot, move back and don't bi-sect head.
Shot 2: Boring... For future, shoot shoes as a product shot showing side as well as toe. Watch background. If shooting shoes on feet, come up with better pose, more dynamic.
Shots 3 & 4: Good shots. Crop tighter for more impact. Cut left side just past brides veil. Get rid of drooping pipe at top of image that doesn't fit the pattern of other pipework.
Shot 5: Bingo! As already commented, be careful not to make all shots too similar with B&G centered.
Shot 6: Great idea that almost works. Vegetation in foreground is too distracting and doesn't fit right as a frame. Background pipe work is disconnected and pulls your eye away from the couple. Tough to be critical when the environment can't be controlled. This shot might be a candidate for off center couple (think rule of thirds perhaps) and different vegetative framing?
Shot 7: Good shot... can you get rid of that concrete pot that blocks grooms back? Crop tighter on groom, put couple off center in shot, overlay this shot with another one to fill the resulting "dead corner." (Draw imaginary line from grooms eyes thru brides eyes and see how it leads to lower right of frame. This can be a great lead-in to another shot when laying out an album.) Not sure that will work, but worth considering.
Shot 8: I know you were trying to create a frame, but leaves at top seem out of place - almost like you were holding them with left hand while shooting with your right. Great idea, just needs some practice to refine.
Shot 9: Others have commented -- watch both sides of arbor, left is vertical, right isn't. Sometimes you just have to split the difference.
Good work, keep learning. And, remember, these are just opinions. Develop your style as you see fit!
