The text could be changed IMO. Im not very fond of typewriter fonts when it comes to lovey quotes xD Unless its a letter theme..
Anyway and with the wedding picture, try practicing with cutting images from their original photo. If you need help with that I can gladly give you a tutorial ^^ But that would allow you to get rid of that blue background around Usagi's hair and it would make the whole thing look cleaner
Hope I helped ^^ Looks very good either way and I do like the quote you chose
