Engagement Picture Fear

At the end of the month Tim and I are getting our engagement pictures taken.

I am a little scared because I tend to make strange looks in posed pictures. As my mother says I tend to look like the cat that swallowed the canary. So I am looking for tips.

I found this: How to Be Photogenic

One of the suggestions is looking at pictures of other people who are photogenic.

Here are some pictures I am looking at for inspiration:
Picture 1
Picture 2
Picture 3


And this is just a sweet wedding moment that I dream of having (with less flowers) at our wedding.

At least Tim is photogenic. He suggests I think of kittens drinking lattes or something like this to make me smile naturally.
