I have to say that something doesn’t work for me here, but maybe it’s just me not getting it..
Because you asked for comments, I give you mine.
I’m not sure what you mean with the title “Sound of Autumn”, i feel you should have tried with something more in the lines of “Colors of autumn”
The leaf would have looked better if it was in her original autumn color, i doubt you found it like that.
I feel there is a lack of sharpness and the highlights are blown out.
Not sure about the blurred people..
Having said that, I can see a potential in the shot but this time didn’t work (for me), sorry ;)
