The reason it may look forced is because it was FREEZING that day hahaha I was in a coat and I was still shivering I am proud of my brave model to risk being so cold it didn't help that she was on a freezing cold rock. ;)
I was surprised when I opened the link to see that this scored as low as it did. Clearly the image met the challenge, so you cannot have received DNMC votes at least :)
For my taste, I find that framing is a little too tight. I would prefer to see a little more space to the left of the image as I look at it. I do agree with some of the comments you have received already about the posing. You model really does look a tad uncomfortable, a little like she is clinging on for dear life.
Although I don't think there is really anything wrong with the exposure, the lighting does feel a bit flat to me.
I am usually not a negative critic however, the pose in your photo is excessivley unflattering to the otherwise attractive model. Instead of alluring and eyecatching, I would expect a pose like this on CSI after just finding a haphazardly dumped body in the woods. Too many other distractions in the greenery, snow, dead trees behind. i've seen this woman used before and very well I might add but this seemed rushed and unthoughtful. Sorry, I hope this is taken in the spirit intended.
I love the dress and the outdoor shot with the snow is an interesting idea. However to my eyes the pose, in particular the position of her legs, seems very awkward and unnatural and detracts from the overall image.
