when taking normal pictures, you're so encouraged not to "cut off the top of my head!" but it is actually it gives off a very intimate vibe. if she had a ring on her finger, it'd be a great engagement shot too!
I love this as an engagement picture. I love that it's not about the ring, or the date, it's about the couple. This is the perfect example of what a perfect engagement pic should be. It also could be a fabulous pic of a couple who are renewing their vows.
