That's exactly my opinion too, it just looks unhealthy and not beautiful at all. The photo quality itself is very good, I like the soft grey colours here and the structure of the wood! But if the model had a healthy weight, it would look so much better to me.
I love all your pics but I gotta say that I hate this one... she's just too tiny and she looks anorexic, this isn't beautiful at all... I feel sad to read in the comments thats some would look like her... anyway, no hate toward you, that was just my opinion You've got the right to think she's beautiful ^^ (and I am sure she is, she's just too thin to me... )
