Autumn Fairy

This is the first time I have ever attempted creating an image like this. I had to create this image as part of an assessment for my photography course. As part of the assessment I need constructive criticism on my work from the charming chaps that tend to frequent this site I would really appreciate it if you could leave a little comment on where I've gone wrong and the improvements that can be made.
