Yep - stressed look captrured nicely, though perhaps not the most flattering of poses for your model! Maybe not enough "beginning" without the title, though.
This image doesn't say 'stressed' to me. I think your title and the image are not too well matched. Within the portraite the background is very distracting and the main focus on the bride's face is her ear (the lightest part). Compositionally this image doesn't really work.
Having said all that its not a bad image, just needs some more thought and some time taken over arranging the main parts. I guess this was taken quickly as a grab shot due to the circumstances and to be honest that shows.
