I love the colour of the hair against the dress. As an image by itself it's lovely and the contrasts of the green trees against the red hair works really well. The pose is nice as it works as a dance as well as a 'twirl' or even a ghostly apparition.
My main problem - from a photo manipulation point - was the grey asphalt against the grey of the dress, it made masking/cutting out VERY difficult.
The whole series is great and imaginative and lends itself well to photo manipulation. I've always found 'pretty' not enough and your images show personality and emotion that is often lacking in other stock images. There's emotional depth and the feeling of 'story' in your images, and this one is no exception. xoxo
