wow. she is stunning, you are very lucky. this really makes the most of natural beauty, she isn't loaded with false makeup, lighting, etc. it's all natural and relaxed, you get a feel of who she really is, rather than playing a part, like so many models are asked to/seem to do in portrait-like photos. for that i admire you.
It's so damn hard to smile in a natural way on demand. I admire everyone who has this powerful ability.
