We love your stuff Susie!! What is "wrong" - I certainly don't count brads or measure mats or anything, and I doubt anyone else does. If its a nice page and people can use it, and you've put some work into it (i.e. not just slapped a piece of paper and a sticker or two) I'm sure it would be fine. Depending on AWM, of course.
ETA I've just looked at your page and wish I was in that group! If you're worried put a hidden journalling box under a mat and the smaller mat can be a photo space, also the slide mount.
