not bad for being your first wedding, but there is a lot that can be improve, were you doing this for fun or were you hired? if you were doing just for fun, cool, but if i was getting pay, i would definatelly start cleaning, cropping and color correcting all those images.
what lens did you use? some of those shots could had been improved if you had use something like a 50mm f1.8, like the ones where the guys are standing in front of the open messy garage, if you take em at f1.8 you would barely see or notice the messy garage and your subject (the person) would stand out more.
you also need to watch your lighting, there is a few pics were the person you were shooting had what they refer to "raccoon eyes", some had a glare on their face, etc.
don't feel bad, weddings are a lot of work and lots of stress, we've been there, just a few things to keep in mind to improve your photography.

just keep shooting!
