I'm really liking your work with your lovely wife! They are getting better all the time. I'd like to make mention of something that I've been watching with her expressions. Most of the previous expressions look very forced and uncomfortable but these have a much more natural feel to them; especially the first one. Her smile looks very genuine and heartfelt. Even the second one has that same feeling to it. The third one looks a little bit forced still. Nevertheless, these look great and she is looking oh-so-fine.
I also really like the other image you posted of her where she was on her hands and knees. She had a very appealing and genuine smile there as well. She looks much more relaxed in the latest photos and it really shows! She is very beautiful and you are a very fortunate guy. My best to the both of you and I look forward to more from the two of you.
