I like the soft back ground and the boldness of the tree. I find the shade concept interesting but the dark water steals the eye too much (to me anyway). I like the sense of direction given to the leaves and branches and I wish that for this massive tree that the root structure got more attention and size. Love the pinkish haze on the horizon and the green highlights on the upper part, light from the sky and sun. The tree is firmly rooted in the image and in my mind. Also, I like the composition and the way you did the flower groups on the left, but the stream leaves me cold the way it wraps around (because of the shadow).
