hey i think you should change your choice of typeface to something more elegant and formal. check these fonts out if you can:

snell roundhand
kunstler script
copperplate gothic - used as small copy (not bold)

also im not so sure about the cartoon kind of theme for a wedding, im picturing nice clear photographs of wine glasses, flowers, etc. with a "light" color theme. the lavender you used is pretty nice

id really like to see an actual invitation graphic on the welcome page. instead of just text on a flat background. you can take a photo of a blank invitation and write the text on the computer so its readable

keep it up though, very nice
congrats
