This is just gorgeous. The colors are beautiful and the light from your subject is enhanced by the surrounding darker and partially blurred background. The bright line of light coming out diagonally from the left lower corner, the hanging moss, the twigs and rocks on the right side. All are so wonderful. This is a perfect example of the negative space enhancing the positive space and is IMO an ideal entry for this challenge. I voted on this before I knew whose it was so I am leaving my score.
Its all a blur so no real focal point and therefore not really positive space in my opinion (positive space being a main focal point standing out from the background)
