The power of this shot is the light! It gives the scene a great atmosphere covering all the tones in it, from red to green passing from brown and yellow.
Elements of composition are strong. The closed eyes of the model contribute to the "dreamfull atmosphere" and the leaves all around make a great background. The leaf on the ear is important to composition thus contribute to detailing the scene; the leaf capture the attention thanks to its erarring appearence.
Why 4 stars?
The head is too much cutted. A little bit of neck inside would have been better.
The 3 leaves on the hair distract a little bit.
I love this composition! Keep on doing great shots!
