the shimmery reflections do not work for me. it takes away the focus on the leaf and creates a lot of distraction. i find my eyes wandering around the photo.
maybe you can use a polarizer and limit the amount of reflections.
maybe include more of the "stream" elements in the picture, like rocks and pebbles.. cos I just see a picture of a leaf in water.. also agree on the shimmering reflections, too distracting..
