Photos of Joy

I am not a wedding photographer and have never claimed to be. I like to do landscapes wildlife, and night photography. That being said if close family or friends ask me to shoot their small wedding I'm probably not going to say no. My girlfriends sister was having a small wedding in Maine and they didn't want to spend a lot of money and asked me to take some photos, so I did. Some of my favorite shots were candid shots where people didn't really know I was there with a camera. I caught the bride here just at the right time as she's looking at her husband with a sly smile on her face. This was my favorite photo out of the almost 700 I took. There's just something about this photo that expresses joy to me. Please let me know what you think in the comments. As someone who's not a wedding photographer at all I'd be interested to here some constructive feedback of this image. Thanks!
