hadji, I think the issue here is that you asked for a critique, then later said it's a spontaneous shot and you like shooting people where they are as they are. This is not that kind of forum. Maybe some forum in flickr, or something?
Not everyone is a professional photographer here, but those who post here and ask for a critique typically expect that level of feedback. We're going to break down every element of your shot, from flyaway hairs to on-camera flash to harsh lighting and over-processing (smoothing) of the skin.
Your model is lovely, but I agree that Josh was simply calling it as it is. As Jim mentioned. As David mentioned.
