Ok so I have finished a great portion of my invitation over the weekend and I am looking for some criticism on everything, wording, design, font, etc.

So here is the design with the stamps on the invite. The stamp at the bottom is a stamp of several shells. It's kinda hard to get a good picture with my crappy camera. What do you think of the stamping (i realize the flowers on top are not fully dark, this is just rough). I was trying to figure out if it's too much or if I should change the flower arrangement, etc. But I think I like it....not sure. WDYT?
Invite Wording:

Response Card:

I'm not really sure about the font on this one.....idk. Ideas?
Information Card:

WDYT about how I worded the registry piece?
Also, what do you think about putting the info on the toasting on there. FI thinks it's fine, and I like it.....but my only apprehension is that we might get too many people asking to toast....
Anyway....there's all that! Please rip it apart and give me advice on making it perfect. Thanks!
