not working for me, its too half-hearted. At this focus range you probably need to be closer to f/1.4 to really melt the background. No clear subject in the composition either, so probably would have better suited a deep DOF approach.
just as a convenient example, this is more the situation I would be thinking about isolating the subject using depth of field.
0673 us my favourite, beautiful scene. Photography is always about the light.
