The styling and costuming of this image is quite good. The model pulls off this look very well. A very candid innocence. Gives me a great sense of the character. Love the cropping at the top, bottom and right. Might consider squaring up the image by cropping square from the left. This will still leave your subject positioned to the right of the image, which I like. Just a thought.
I like the composition, the way you have divided your subject from the leaves in the background. The stem next to the models face is a bit distracting. Nice Job.
