I agree with the shine on the face being too much. I also notice that the water she's in is "smoth as glass" but there are two waterfalls near her. You've done a great job by adding the mist but I think the water itself needs more turbulence where she's standing. I with I could recommend a way to do that but I don't know how - unless you take apart a real photo in Photoshop and layer it around her(?????).

Before they made me they broke the mold!
